Book excerpt: Nitrogen based monodentate and bidentate chelating ligands have captured a significant interest due to their ability to coordinate to a wide variety of elements. The â-diketimine, â-ketoiminato, formamidine, pyridineselenolate, and pyrazinecarboxamide ligands have all been employed in this study to further investigate the coordination preferences among main group and transition metals. Steric and electronic properties of these ligands can easily be altered by manipulating the substituents attached, thus leading to predictable structures with potential for many useful and significant applications. Investigations have shown that temperature, solvent, and metal halide employed are all key factors in the reaction outcomes. All of the complexes obtained throughout these studies have been characterized by X-ray crystallography along with other spectroscopic techniques, including NMR, IR, UV/Vis, and M/S. â-diketiminato ligands, [{N(R)C(Me)}2C(H)] where R = Dipp, Mes, commonly referred to as nacnac, have played an important role in the synthesis of novel pnictogenium complexes. Results show that through manipulation of the halide precursor, reaction stoichiometry, and the R substituent on the nacnac both N, N'- and N, C'-metal chelated complexes can be achieved. Additionally, â-ketiminato ligands, [RN(H)(C(Me))2C(Me)=O] where R = Dipp, and [RN(H)C(Me)CHC(Me)=O] where R = C2H4NEt2, have been studied. Both ligands were investigated with a range of d and p block metal halides and alkyls in order to compare and contrast the bulky, flexible, and even multi-dentate nature of each ligand. The preferred metal geometry remains constant for products with either ligand, but the steric protection offered by the individual ligands governs the nuclearity of the products, ranging from tetrameric cages to simple adducts. The formamidinate ligand, [RN(H)C(H)NR] where R = Dipp, was employed in synthesizing several aluminum and zinc complexes. In addition to their numerous applications as cata.

This book was released on 2010-05-27 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bis(phosphinimino)methanide rare earth metal bisborohydrides, as illustrated in Scheme I, were successfully synthesized by salt metathesis reactions of [K{CH(PPh2NSiMe3)2}] with [Ln(BH4)3(THF)n] (Ln = Sc (n = 2); Ln = La, Nd, Lu (n = 3)) or in the case of yttrium by the reaction of [{(Me3SiNPPh2)2CH}YCl2]2 with NaBH4. Interestingly, the BH4- anions are ?3-coordinated in the solid state structures of 3, 4, 6 and 7, while for the scandium complex 5 two different conformational polymorphs were identified, in which either both BH4- groups are ?3-coordinated or one BH4- anion shows an ?2-coordination mode. Furthermore, complexes 3, 6 and 7 showed high activities in the ring-opening polymerization (ROP) of e-caprolactone (CL). At 0 °C, the molar mass distribution reached the narrowest values ever obtained for the ROP of CL initiated by a rare earth metal borohydride species. In collaboration with N. Meyer, rare earth metal chlorides and borohydrides of the 2,5-bis{N-(2,6-diisopropylphenyl)iminomethyl}pyrrolyl ligand were synthesized, as shown in Scheme II. The reaction of [(DIP2pyr)K] (10) with anhydrous neodymium trichloride afforded [(DIP2pyr)NdCl2(THF)]2 (12) which is dimeric in the solid state. Excitingly, the reaction of [(DIP2pyr)K] (10) with [Ln(BH4)3(THF)n] (Ln = Sc (n = 2); Ln = La, Nd, Lu (n = 3)) depends on the ionic radii of the center metals. For the larger rare earth metals lanthanum and neodymium, the expected products [(DIP2pyr)Ln(BH4)2(THF)2] (Ln = La (13), Nd (14)) were obtained; while for the smaller rare earth metals scandium and lutetium, an unusual redox reaction of a BH4- anion with one of the Schiff-base functions of the ligand was observed and the products [{DIP2pyr*-BH3}Ln(BH4)(THF)2] (Ln = Sc (15), Lu (16)) were formed (Scheme II). Moreover, the two neodymium containing complexes 12 and 14 were investigated as Ziegler-Natta catalysts for the polymerization of 1,3-butadiene to form poly-cis-1,4-butadiene, by using various cocatalyst mixtures. Very high activities and good selectivities were observed for 12. The 2,5-bis{N-(2,6-diisopropylphenyl)iminomethyl}pyrrolyl ligand was successfully introduced into the coordination chemistry of the divalent lanthanides and the alkaline earth metals. As shown in Scheme III, salt metathesis reactions of [(DIP2pyr)K] (10) with either anhydrous lanthanide diiodides or alkaline earth metal diiodides afforded the corresponding heteroleptic iodo complexes [(DIP2pyr)LnI(THF)3] (Ln = Sm (19), Eu (20), Yb (21)) or [(DIP2pyr)MI(THF)n] (M = Ca (24), Sr (22) (n = 3); Ba (23) (n = 4)). Surprisingly, all complexes 19-24 are monomeric in the solid state, independently from the ionic radii of their center metals. Instead of forming dimers, the coordination sphere of each metal center is satisfied by additionally coordinated THF molecules, which is a very rare structural motif in the chemistry of the larger divalent lanthanides and alkaline earth metals. While the (DIP2pyr)- ligands in 19-23 are ?3-coordinated in the solid state, for the calcium complex 24 an ?2-coordination mode was observed (Scheme III). Interestingly, the calcium complex 24 and the analogous ytterbium compound 21 show different structures in the solid state. In order to obtain catalytically active species, [(DIP2pyr)M{N(SiMe3)2}(THF)2] (M = Ca (25), Sr (26)) were prepared by the reaction of [(DIP2pyr)MI(THF)3] (M = Ca (24), Sr (22)) with [K{N(SiMe3)2}] (Scheme IV). Compounds 25 and 26 were investigated for the intramolecular hydroamination of aminoalkenes and one aminoalkyne. Unfortunately, both catalysts exhibit a limited reaction scope, caused by the formation of undesired side products by alkene isomerization and imine-enamine tautomerism. However, both compounds are active catalysts and show high yields and short reaction times. The highest activities were observed for the calcium complex 25 and can be compared to the results obtained with the ß-diketiminato calcium amide [{(DIPNC(Me))2CH}Ca{N(SiMe3)2}(THF)] as a catalyst. Finally, imidazolin-2-imide and cyclopentadienyl-imidazolin-2-imine rare earth metal alkyl complexes, synthesized by M. Tamm et al., were investigated for the intramolecular hydroamination of non-activated aminoalkenes and one aminoalkyne. Both compounds showed high selectivities and activities, and although they cannot compete with the metallocene analogues, the imidazolin-2-imide complexes are new and interesting examples for catalytically active post-metallocenes.

This book was released on 2015 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is primarily concerned with the synthesis of low oxidation state alkaline earth metal complexes featuring novel [beta]-diketiminate ligands and their derivatives. The syntheses of a variety of different [beta]-diketiminates possessing extreme steric bulk, as well as those that have been electronically modified are detailed. These ligands have been used to produce a variety of different alkali metal, alkaline earth metal and lanthanide complexes.Chapter 1 provides a general introduction to low oxidation state alkaline earth metal chemistry. Particular attention is given to metal complexes featuring [beta]-diketiminates, given their central role in the research making up this thesis.Chapter 2 deals with the synthesis of a range of novel, sterically hindered [beta]-diketimines. These pro-ligands were targeted in the belief that their extreme bulk would allow the synthesis of currently unknown structural motifs.Chapter 3 is primary concerned with the exploitation of the developed sterically hindered [beta]-diketimines in the synthesis of a variety of alkali metal, alkaline earth metal and lanthanide complexes. A range of three coordinate magnesium complexes were produced using the developed ligands, most notably, the first crystallographically characterised [beta]-diketiminato magnesium hydride. In our quest for a calcium(I) dimer, a complex type which is currently unknown, a variety of [beta]-diketiminato calcium iodides were produced. The attempted reduction of these heteroleptic metal iodide complexes resulted not in the targeted low oxidation state complexes, but in two different calcium(II) dimers.In Chapter 4, the [beta]-diketimine ligand was adapted, resulting in two separate classes of pro-ligands. The first, a 1,3,5-triazapentadiene, has had the central carbon replaced by nitrogen. The second, instead of having the typical methyl groups on the ligand backbone, has dialkylamino groups. In each instance, it was envisaged that the ligands would donate additional electron density, and bind more strongly to the metal centre in coordination complexes, when compared to the standard [beta]-diketiminate ligand class. Six separate heteroleptic magnesium(II) iodide complexes have been developed from these ligands, the majority of which show promise as precursors to low oxidation state magnesium complexes.Chapter 5 details several new secondary amines which have been produced as pro-ligands for low oxidation state main group chemistry. In addition, preliminary studies have shown that these ligands have potential in coordination chemistry.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this Thesis is on the synthesis and characterisation of aryloxides of the lanthanoid and alkaline earth metals with an emphasis on structural characterisation. One of the key objectives has been to explore the boundaries of the redox transmetallation/protolysis (RTP) reaction (formerly known as redox transmetallation/ligand exchange), and this is the focus of Chapter 2. Redox transmetallation/protolysis reactions were performed in the non-donor solvents toluene and hexane, in which success has not previously been achieved, and the reaction rates monitored by 19F NMR spectroscopy. A donor-solvent free pathway is proposed in which an intermediate of the type [Ln(C6F5)2(HOAr)n] is formed, and plays a pivotal role in determining the speed of the reaction. The application of this method for the synthesis of homoleptic products was established by the synthesis of the known homoleptic compounds [Ln(2,6-dpp)3] (Ln = La, Pr, Nd), [Ba2(2,6- dpp)4] (2,6-dppH = 2,6-diphenylphenol) and [La(2,6-dip)3]2 (2,6-dipH = 2,6- diisopropylphenol) as well as the isolation of new compounds [La4(3,5-dbp)12(3,5- dbpH)] and [Nd4(3,5-dbp)12(3,5-dbpH)]/[Nd4(3,5-dbp)10(3,5-dbpH)4(OH)2] (3,5- dbpH = 3,5-di-tert-butylphenol). A series of lanthanoid aryloxide complexes of the type [Ln(2,4-dbp)3(THF)3] (Ln = La, Pr, Nd, Gd, Er) were prepared by RTP reactions with 2,4-di-tert-butylphenol (2,4-dbpH) and structurally characterised (Chapter 3). Reaction in DME with neodymium afforded the seven-coordinate [Nd(2,4-dbp)3(DME)2], while the dinuclear [Yb2(2,4-dbp)6(DME)2] was obtained by an analogous reaction with ytterbium. Recrystallising the THF derivatives from toluene or hexane resulted in the loss of THF and the formation of the dinuclear [Ln2(2,4-dbp)6(THF)2] (Ln = Nd, Er). The structurally similar [Nd2(2,4-dbp)6(2,4-dbpH)2] was the product of a thermally induced protolysis reaction between the metal and the phenol. A RTP reaction between ytterbium metal and 2-tert-butylphenol (2-tbpH) did not give a solid product, however, the complex [Yb2(2-tbp)6(THF)2] was obtained after crystallisation from toluene. Extending this chemistry to the heavy alkaline earth metals, calcium, strontium and barium resulted in the isolation of a group of new and interesting compounds ii (Chapter 4). Reactions in THF afforded [Ca(2,4-dbp)2(THF)4] and [Sr3(2,4- dbp)6(THF)6], while analogous reactions in DME gave the remarkable [Ca2(2,4- dbp)4(DME)5], containing a bridging molecule of DME, and the asymmetrically bridged [Sr2(2,4-dbp)4(DME)3]. Reactions with the larger barium yielded cluster complexes [Ba8(2,4-dbp)12(OH)4(DME)4] and [Ba8(2,4-dbp)12(OH)4]. Chapter 5 details the synthesis and characterisation of a series of lanthanoid and alkaline earth calixarene complexes. Reactions between the lanthanoid metals and p- But-calix[4]arene in the presence of bis(pentafluorophenyl)mercury yielded [Ln(calix[4]OH)(THF)]2 complexes (Ln = Nd, Yb). Attempts to isolate divalent products through the strategic use of the p-But-calix[4](Et)2(OH)2 were unsuccessful, instead affording a series of chloride-containing complexes of the type [Ln(calix[4]Et2)Cl(THF)]2, in which the presence of the chloride arose from contamination of the starting material. A reaction between strontium metal and p- But-calix[4](OH)4 in the presence of bis(pentafluorophenyl)mercury afforded [Sr4(calix[4](OH)2)4(OH2)4(THF)4] after partial hydrolysis. A number of compounds prepared in the course of this work ([Nd(2,4- dbp)3(THF)3], [Gd(2,4-dbp)3(THF)3], [Ca2(2,4-dbp)4(DME)5], [Sr2(2,4- dbp)4(DME)3]) as well as the known compounds [Yb(ttfpz)2(THF)4], [Sm(dippForm)2(THF)2], [La(xylForm)3(THF)], [Sm(xylForm)3] and [Sm(mesForm)3] were taken to Oxford University and tested as potential initiators for the ring-opening polymerisation of rac-lactide. All were found to be capable of initiating polymerisation, albeit with varying degrees of success. Most systems could be improved by the introduction of a co-initiator (or chain-transfer agent) such as benzyl alcohol or benzylamine to promote immortal polymerisation. Chapter 6 provides detailed discussions of the polymer features, as well as kinetics studies of the rate of polymerisation in the cases of [Nd(2,4-dbp)3(THF)3], [Ca2(2,4- dbp)4(DME)5], [Sr2(2,4-dbp)4(DME)3] and [Sm(dippForm)2(THF)2] in the presence of benzylamine. Furthermore a structure-activity relationship for the alkaline earth initiators is discussed.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the nature of the work undertaken during the course of this PhD, the results of this thesis will be broken down into three sections. The first section comprises Chapter 1 and includes an introduction on reported homometallic lithium, sodium and potassium salts of the bulky utility amines [HMDS(H), TMP(H) and DA(H)]. The second section, Chapter 2−Chapter 5, includes the achieved results obtained during the course of this PhD work based on the homometallic alkali metal building block amides. The third section involves an introduction on zirconium species and their applications in specific reactions, along with the solid and solution state studies of zirconocene species combined with alkali metal and alkali earth metal amides obtained during this work.Chapter 2 includes a deep discussion in the solid state of NaHMDS systems capturing Na halide units in the presence of a multidentate Lewis base donor ligand, taking on different structural guises depending on the denticity of the ligand of choice. This topic is currently a hot topic in organometallic chemistry, being lithium amide congeners have already been characterised. This study allows a deep examination of these structures and confirms the AM-amide/AM-halide interaction to exist in sodium chemistry as well.Chapter 3 unveils the structural chemistry of the utility base, potassium hexamethyldisilazide (KHMDS), which is explored through the incorporation of different dentate ligands into its structure. This study containing the solid state characterisation of homometallic potasium amides being a necessary preface to the bimetallic work. Having investigated the solid state structure of homometallic potasium systems, it was also deemed important to study heavier alkali metal building blocks. Thus, Chapter 4 includes the structural characterisation of specific amine adducts of the heavy alkali metal amide CsHMDS, which is recently being used in important organic transformations. Having investigated homometallic systems of heavy bulky amides, it was also deemed important to synthesise and characterise heterobimetallic species containing early and heavy alkali metal species adding to the solvent-coordination free heterobimetallic alkali metal building blocks. Due to the usage that sodium hexamethyldisilazide (NaHMDS) is gaining as a proton abstractor reagent in organic synthesis, akin to its homometallic lithium congener LiHMDS, Chapter 5 includes the synthesis and structural characterisation of three novel adducts of NaHMDS by using the chiral amine N,N,Nʹ,Nʹ-(1R,2R)-tetramethylcyclohexane-1,2-diamine [(R,R)-TMCDA] and the synthetically important tridentate ligand PMDETA allowing the development of a homologues series of [(R,R)-TMCDA]- and PMDETA-solvated NaHMDS complexes. Having successfully synthesised solvated homo- and hetero-bimetallic alkali metal salts of HMDS, the attention turned to the possibility of incorporating the tetravalent transition metal zirconium into these systems to afford homo- and hetero-bimetallic HMDS-containing zirconocene species (Chapter 6).

Book excerpt: Nowadays, the ability to synthesize new bioinspired metal catalysts to improve and broaden the spectrum of catalytic activity is of paramount importance for sustainable chemistry respectful for our environment. This thesis is focused on the design of transition metal complexes (copper and palladium) based on two different classes of organic ligands: benzotriazolyl-phenolates and phosphonates.Different original complexes based on palladium and copper were synthetized from benzotriazolyl-phenolate and phosphonates ligands. The characterization of the new compounds was performed by different physical and physico-chemical methods (electrochemistry, EPR, UV-vis, IR, X-ray crystallography) and quantum chemistry. The generation and characterization of different reduced and oxidized species helped us in the possible mechanisms determination. The obtained compounds were successfully employed as catalysts in different processes as: hydrogen production, alcohol oxidation and DNA cleavage.
