Book excerpt: Ligand design in general enables the formation of coordination compounds with multiple functionalities within a single framework. To date, two of the most widely studied ligands are 2,2':6',2''-terpyridine (terpy) and acetylacetone (acac), whose tridentate and bidentate coordination pockets, respectively, enables the formation of metallic complexes with various geometries. The Brusso group had been incorporating imidoyl amidine (ImAm) ligands to build different materials such as organic radicals and fluorescent materials. In particular, the ligands N-2-pyridylimidoyl-2-pyridylamidine (Py2ImAm) and N-2-pyrimidylimidoyl-2-pyrimidylamidine (Pm2ImAm) were recently synthesized and have great appeal to build metallic complexes, as they poses two coordination sites similar to those in terpy and acac. The work presented herein represents the first studies involving the coordination of Py2ImAm and Pm2ImAm as discrete ligands. Our results demonstrate the versatility of these ligand frameworks, in which discrete mononuclear complexes, homometallic and heterometallic polynuclear complexes may be realized. Chapter one serves as a brief introduction to transition metal chemistry and has a comprehensive review of the coordination chemistry of the ImAm ligand framework. In chapter two, the selective coordination of first row transition metals into the bidentate or tridentate sites of Py2ImAm is explored. The formation of these mononuclear complexes is acid-base driven, where a weak acid induces coordination to the tridentate site and a weak base leads to coordination in the bidentate site. Coordination to both sides of Pm2ImAm with manganese or iron is explored in chapter three. The results show the formation of unusual tetranuclear complexes with the metal ions in both low spin and high spin configurations. Chapter four covers the coordination to cobalt, and the formation of polynuclear complexes with different geometries using Pm2ImAm. The magnetochemistry of these cobalt polynuclear complexes is also presented and reveal a single molecule magnet behaviour for one of the complexes. Finally, in chapter five, a one-pot synthesis of copper-manganese heterometallic complexes is presented. Overall, these imidoyl amidine ligands are able to build complexes with different geometries, different electronic configurations (i.e. low or high spin), and different metal ions. These results show a great versatility of ImAm ligands and suggest the future use of these ligands by other research groups.
Book Synopsis The Chemistry of Imidoyl Halides by : Henri Ulrich
Download or read book The Chemistry of Imidoyl Halides written by Henri Ulrich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Primarily, the aim of this book is to provide a reference work for senior students and research workers engaged in the synthetic aspects of chemistry. The various classes of compounds under discussion provide useful interme diates for the synthesis of numerous nitrogen-containing derivatives. Imidoyl halides are also intermediates in several classical name reactions, such as the Gattermann, Houben-Hoesch, and Vilsmeier-Haack syntheses of aldehydes and ketones, the Beckmann rearrangement, and the v. Braun degradation. Some imidoyl halides have shown interesting agricultural activities, and the generation of highly reactive species (ketenimines, nitrile oxides, nitrile imides, carbodiimides, etc.) from imidoyl halides has contributed to the study of polar cycloaddition reactions. To enable researchers to utilize this chemistry without consulting the original references, I have included a number of selected working examples. This procedure will facilitate the transformation of written information into well designed experiments, especially since part of the cited literature is not readily available. The book is organized around classes of imidoyl halides, with synthesis and chemistry discussed in an orderly fashion. The physical properties of the known imidoyl halides are listed in tables, and I have attempted to draw attention to the more recent literature. The one or two references provided for each compound represent those which best describe its physical constants and synthesis.

Book Synopsis Synthesis of Chiral Rare Earth and Alkaline Earth Compounds by : Meng He
Download or read book Synthesis of Chiral Rare Earth and Alkaline Earth Compounds written by Meng He and published by Cuvillier Verlag. This book was released on 2016-08-16 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first chiral amidinate borohydride rare earth compounds and compounds based on (S)-HPEBA ((S,S)-N,N-bis-(1-phenylethyl)benzamidine) ligand were reported by Roesky et al. To continuing this work, the new chiral ligand (S)-HNEBA ((S,S)-N,N-bis-(1-naphthylethyl)benzamidine) were synthesized. The corresponding amidinate metal complexes were successfully obtained by amine elimination. The luminescent and magnetic properties of rare earth compounds were studied. Alkaline earth metal compounds have been extensively studied as catalysts in synthetic chemistry. However, chiral amidinate alkaline earth metal complexes have never been reported. Chiral amidinate ligand (S)-HPEBA was introduced into the coordination chemistry of the alkaline earth metal as well as divalent lanthanides, their catalytic activities in hydrophosphination have been investigated. The Ba compound showed high catalytic activities in the hydrophosphination reaction. Moreover, since rare earth metal COT complexes exhibit excellent SMM behavior, it is of great interest to study the magnetic behavior of COT amidinate complexes. Thus, amidine ligand (S)-HPEBA and (S)-HPETA are introduced into the corresponding COT amidinate complexes for magnetic properties studies. The Er Compound exhibited typical field-induced SMM behavior. Furthermore, inspired by the promising application of lanthanide SMMs and the research of SMMs based on sandwich type lanthanide complexes, a series of novel sandwich type complexes comprising of Pc and COT ligand were designed and synthesized.

Book Synopsis Metals and Non-metals by : Navjeet Kaur
Download or read book Metals and Non-metals written by Navjeet Kaur and published by CRC Press. This book was released on 2020-01-28 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities—chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a ‘foundational pillar’ of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.
