This book was released on 2017-04-17 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Organometallic Chemistry of N-heterocyclic Carbenes describes various aspects of N-heterocyclic Carbenes (NHCs) and their transition metal complexes at an entry level suitable for advanced undergraduate students and above. The book starts with a historical overview on the quest for carbenes and their complexes. Subsequently, unique properties, reactivities and nomenclature of the four classical NHCs derived from imidazoline, imidazole, benzimidazole and 1,2,4-triazole are elaborated. General and historically relevant synthetic aspects for NHCs, their precursors and complexes are then explained. The book continues with coverage on the preparation and characteristics of selected NHC complexes containing the most common metals in this area, i.e. Ni, Pd, Pt, Ag, Cu, Au, Ru, Rh and Ir. The book concludes with an overview and outlook on the development of various non-classical NHCs beyond the four classical types. Topics covered include: Stabilization, dimerization and decomposition of NHCs Stereoelectronic properties of NHCs and their evaluation Diversity of NHCs Isomers of NHC complexes and their identification NMR spectroscopic signatures of NHC complexes normal, abnormal and mesoionic NHCs The Organometallic Chemistry of N-heterocyclic Carbenes is an essential resource for all students and researchers interested in this increasingly important and popular field of research.

Available in PDF, EPUB and Kindle. Book excerpt: N-heterocyclic carbenes (NHCs) have found increasing use as reagents for a range of organic transformations and in asymmetric organocatalysis. The performance of these molecules can be improved and tuned by functionalisation. Functionalised carbenes can anchor free carbenes to the metal site, introduce hemilability, provide a means to immobilise transition metal carbene catalysts, introduce chirality, provide a chelate ligand or bridge two metal centres. NHC can be attached to carbohydrates and campher, derived from amino acids and purines, they can be used as organocatalysts mimicking vitamin B1 or as weak “solvent” donors in lanthanide chemistry. Functionalised N-Heterocyclic Carbene Complexes describes major trends in functionalised NHC ligands, aiming to assist readers in their attempts to develop and apply their own functionalised carbenes. After an introduction to the chemistry and behaviour of NHC, the book gives a detailed description of functionalised carbenes and their complexes according to a range of functional groups, each with a discussion of the synthetic route, structure, stability and performance. Functionalised N-Heterocyclic Carbene Complexes is an essential guide to fine-tuning this important class of compounds for practitioners, researchers and advanced students working in synthetic organometallic and organic chemistry and catalysis.

Available in PDF, EPUB and Kindle. Book excerpt: Pincer complexes are formed by the binding of a chemical structure to a metal atom with at least one carbon-metal bond. Usually the metal atom has three bonds to a chemical backbone, enclosing the atom like a pincer. The resulting structure protects the metal atom and gives it unique properties.The last decade has witnessed the continuous growth in the development of pincer complexes. These species have passed from being curiosity compounds to chemical chameleons able to perform a wide variety of applications. Their unique metal bound structures provide some of the most active catalysts yet known for organic transformations involving the activation of bonds. The Chemistry of Pincer Compounds details use of pincer compounds including homogeneous catalysis, enantioselective organic transformations, the activation of strong bonds, the biological importance of pincer compounds as potential therapeutic or pharmaceutical agents, dendrimeric and supported materials. * Describes the chemistry and applications of this important class of organometallic and coordination compounds* Covers the areas in which pincer complexes have had an impact* Includes information on more recent and interesting pincer compounds not just those that are well-known

Available in PDF, EPUB and Kindle. Book excerpt: Dimeric rhodium N-heterocyclic carbene (NHC) complexes [Rh(NHC)(C2H4)Cl]2 react with a variety of other neutral donors to form heteroleptic complexes [(L)Rh(NHC)(C2H4)Cl] (L = phosphine, pyridine) or [(L)Rh(NHC)Cl] (L = 2,2'-bipyridine (bipy), 1,10-phenanthroline (phen)). The reactivity of the resulting complexes towards O2 was investigated. In particular, [(bipy)Rh(NHC)Cl] and [(phen)Rh(NHC)Cl] resulted in RhIII peroxo complexes. In contrast, [Rh(NHC)2(O2)Cl] display particularly short O-O bond lengths and are described as singlet oxygen species. Interestingly, the mode in which O2 binds is associated with the coordination number about the transition metal complex, which is related to its reducing power. [Rh(IPr)(C2H4)Cl]2 reacts with phenyl pyridine derivatives at room temperature resulting in formal C-H activations. Upon the treatment of phenyl pyridine with pinacol borane (HBPin) in the presence of a weak base and a catalytic amount of [Rh(IPr)(C2H4)Cl]2, C-H borylated products were obtained in high yield and selectivity. The borylated products can then be used as substrates in the palladium catalyzed Suzuki-Miyaura cross coupling with aryl halides. 1,2,3-Triazole mesoionic carbene (tMIC) ligands were generated upon treatment of corresponding triazolium salts with strong bases, and can be trapped in the presence of a transition metal. The synthesis of Ag-tMIC complexes proceeds by a facile and mild route upon treatment of the triazolium salt with Ag2O. The resulting Ag-tMIC complexes undergo facile transmetallation to both Pd and Rh under very mild conditions resulting in air and moisture stable metal complexes. Triazolium salts can further be metallated to Pd in the presence of weak bases, and the resulting Pd-tMIC complexes are active catalysts in the Mizoroki-Heck reaction with aryl iodides. Benzylic trifluoromethyl sulfones are competent electrophilic substrates in palladium catalyzed cross coupling reactions, resulting in the formation of triarylmethanes in high yields under mild conditions. These substrates are conveniently synthesized and are highly reactive starting materials with phenyl boronic acids in the presence of a Pd-NHC catalyst. The structure of the Pd-NHC precatalyst is crucial, as only [(NHC)Pd(allyl)Cl] type complexes appear to be effective. These complexes can be conveniently synthesized upon the treatment of the corresponding imidazolium salt with a strong base and [Pd(allyl)Cl]2.
