My lab mates were very important to my success as were my colleagues from other synthetic laboratories. My family s support throughout this test of endurance was also very important. The use of fossil fuels is well documented since the dawn of technology. Much of early forms of fossil fuels were coal, and oil. Only in the past 150 years have coal, natural gas, and petroleum grown to their more principal roles as sources of usable energy.1 The expansion and full realization of the petrochemical industry can be considered one of the greatest technological success stories.

Download or read book Development of Novel Rhodium and Iridium Complexes with a Fac-chelating Ligand for Electrophilic C-H Activation written by Jennifer Lee Rhinehart and published by . This book was released on 2011 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Several new bis-3,5(dimethylpyrazol-1-yl)acetate rhodium and iridium complexes were synthesized from MCl3?H2O. [Rh(bdmpza)Cl3]- was isolated with three different cations, lithium, sodium and tetraethylamonium, to obtain a full characterization profile. Analogously, [Ir(bdmpza)Cl3]- was isolated with two different cations, lithium and sodium, and characterized by 1H NMR, 13C NMR, elemental analysis and X-ray crystal structure determination. A neutral rhodium complex, [Rh(bdmpza)Cl2(py)], was also isolated as two isomers by addition of pyridine. Reaction of [Rh(bdmpza)Cl3]- and [Rh(bdmpza)Cl2(py)] with dimethylzinc afforded three new complexes, [Rh(bdmpza)Cl2(Me)]-, [Rh(bdmpza)Cl(Me)2]- and [Rh(bdmpza)Cl(Me)(py)]. Stoichiometric and catalytic C-H activation of benzene was investigated for these new rhodium methyl complexes. Novel rhodium and iridium precatalysts catalysts, [Rh(bdmpza)Cl3]- Na+, [Ir(bdmpza)Cl3]- Na+ and [Rh(bdmpza)Cl2(py)], were subjected to H/D exchange conditions with benzene and deuterated trifluoroacetic acid, acetic acid and methanol in the presence of a halide abstractor. Optimum conditions of silver triflate, deuterated trifuoroacetic acid, 100°C and 24 hours were identified to conduct arene H/D exchange studies. Most arenes investigated showed modest H/D exchange in the ring, while branched [beta]-sp3C-H bonds also showed affinity for H/D exchange. Mechanistic studies of [beta]-sp3C-H H/D exchange were carried out, including synthesis of [Rh(bdmpz)Cl3(py)], which does not contain the pendant acetate group"--Leaf vi.
Book Synopsis Iridium Complexes as Highly Active Catalysts for Hydrogen Isotope Exchange and Hydrogen Borrowing Processes by : Philippa Kate Owens

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last several decades, the organic chemistry community has become increasingly reliant upon iridium catalysis, with applications reported across a number of research areas. In recent years, the Kerr group has developed a series of iridium complexes, which were found to be excellent catalysts for hydrogen isotope exchange and olefin hydrogenation processes. The work described within this thesis centres upon the expansion of these catalysts' reactivity in hydrogen isotope exchange, as well as the synthesis and application of a series of novel iridium complexes, designed for use in hydrogen borrowing catalysis. Chapter one focuses on the development of three efficient and selective methods for hydrogen isotope exchange. Iridium(I) catalysts previously developed within the group have been employed in the successful deuteration of N-heterocycles, which represent an important and relatively underexplored class of labelling substrates. The labelling of a large range of indole, pyrrole, and quinoline derivatives is reported, in which the regioselectivity can be controlled through careful choice of N-protecting group. Extensive practical and computational mechanistic investigations offered insight into the mechanism of indole C3 labelling, which is believed to proceed via an iridium-indoline intermediate. In chapter two, the design and synthesis of a series of novel unsymmetrical NHC ligands, functionalised with electron donating substituents, is described. The corresponding neutral iridium NHC/halide complexes were prepared, and the steric and electronic properties of the ligands were investigated using a number of techniques. These novel complexes were then tested in the catalysis of hydrogen borrowing processes. Extensive optimisation led to the development of an efficient method for the room-temperature N-alkylation of anilines. This methodology was also expanded to include the synthesis of N-heterocycles viaintramolecular C-N bond formation, albeit using more forcing conditions. Lastly, a small series of chiral NHC ligands was designed, and their corresponding iridium complexes prepared and used in a preliminary screening of asymmetric hydrogen borrowing.
Book Synopsis On the Design and Further Applications of Iridium (I) Complexes in Hydrogen Isotope Exchange Processes by : Marc Reid
Download or read book On the Design and Further Applications of Iridium (I) Complexes in Hydrogen Isotope Exchange Processes written by Marc Reid and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new synthetic procedure for isolation of three established Kerr group catalysts has been successfully developed. The final yield of these catalysts has now been improved beyond those published in the literature, and has allowed for the commercialisation of such catalysts for the first time. The synthesis of a series of iridium(I) complexes of the type [(COD)Ir(IMes)(PPh3)]X (X = BF4, OTf, and BArF) has been established. Application of these species in hydrogen isotope exchange (HIE) processes revealed more efficient catalysis and a wider solvent scope when X = BArF. Additionally, these findings have allowed for the development of a novel method for ortho-HIE in unprotected tetrazoles under basic conditions, revealing a rare account of N-H tetrazole C-H activation and a new mode of reactivity for Kerr group HIE catalysts. Towards predictive catalyst design, a combined experimental and theoretical model has been developed to describe the impact of ligand combinations on catalyst performance. Experimentally, this has resulted in a further broad range of novel NHC/phosphine iridium carbonyl complexes, as well as a catalyst 'quick screen' method based on in-situ formation of Ir dihydride complexes. Computationally, novel parameters have been assessed, culminating in a combined ligand map derived from Principal Component Analysis (PCA) of 140 DFT-optimised iridium complexes. Ligand mapping methods have been employed to assess the use of natural product Lepidiline A as a NHC ligand precursor in novel HIE catalysts, revealing the almost purely electronic influence of 4,5-dimethyl substitution on the imidaz-2-ylidene ring. The PCA model has also highlighted complexes of the type [(COD)Ir(NHC)Cl] to be promising in delivering orthogonal reactivity to the now traditional NHC/phosphine pairing. This analysis has led to the realisation of the first regio- and chemoselective catalytic labelling methods for primary sulfonamides and aldehydes. Finally, a novel, one-parameter approach has been developed to describe chelating and monodentate ligand spheres on the same comparable and quantifiable footing. Chelating NHC/phosphine-ligated iridium catalysts have been designed, synthesised, and successfully applied to ortho-labelling of previously inaccessible sulfones, secondary sulfonamides, and bulky tertiary amides.

Book Synopsis N-Heterocyclic Carbenes by : Silvia Diez-Gonzalez
Download or read book N-Heterocyclic Carbenes written by Silvia Diez-Gonzalez and published by Royal Society of Chemistry. This book was released on 2016-11-04 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: In less than 20 years N-heterocyclic carbenes (NHCs) have become well-established ancillary ligands for the preparation of transition metal-based catalysts. This is mainly due to the fact that NHCs tend to bind strongly to metal centres, avoiding the need of excess ligand in catalytic reactions. Also, NHC‒metal complexes are often insensitive to air and moisture, and have proven remarkably resistant to oxidation. This book showcases the wide variety of applications of NHCs in different chemistry fields beyond being simple phosphine mimics. This second edition has been updated throughout, and now includes a new chapter on NHC‒main group element complexes. It covers the synthesis of NHC ligands and their corresponding metal complexes, as well as their bonding and stereoelectronic properties and applications in catalysis. This is complemented by related topics such as organocatalysis and biologically active complexes. Written for organic and inorganic chemists, this book is ideal for postgraduates, researchers and industrialists.
