Understanding Organometallic Reaction Mechanisms And Catalysis from the Author: Valentin P. Ananikov. Exploring and highlighting the new horizons in the studies of reaction mechanisms that open joint application of experimental studies and theoretical calculations is the goal of this book. The latest insights and developments in the mechanistic studies of organometallic reactions and catalytic processes are presented and reviewed. The book adopts a unique approach, exemplifying how to use experiments, spectroscopy measurements, and computational methods to reveal reaction pathways and molecular structures of catalysts, rather than concentrating solely on one discipline. The result is a deeper understanding of the underlying reaction mechanism and correlation between molecular structure and reactivity. The contributions represent a wealth of first-hand information from renowned experts working in these disciplines, covering such topics as activation of small molecules, C-C and C-Heteroatom bonds formation, cross-coupling reactions, carbon dioxide converison, homogeneous and heterogeneous transition metal catalysis and metal-graphene systems. With the knowledge gained, the reader will be able to improve existing reaction protocols and rationally design more efficient catalysts or selective reactions. An indispensable source of information for synthetic, analytical, and theoretical chemists in academia and industry.

Computational Organometallic Chemistry from the Author: Olaf Wiest. Computational methods have become an indispensible tool for elucidating the mechanism of organometallic reactions. This snapshot of state-of-the-art computational studies provides an overview of the vast field of computational organometallic chemistry. Authors from Asia, Europe and the US have been selected to contribute a chapter on their specialist areas. Topics addressed include: DFT studies on zirconium-mediated reactions, force field methods in organometallic chemistry, hydrogenation of ¤Ç-systems, oxidative functionalization of unactivated C-H bonds and olefins, the osmylation reaction, and cobalt carbonyl clusters. The breadth and depth of the contributions demonstrate not only the crucial role that computational methods play in the study of a wide range of organometallic reactions, but also attest the robust health of the field, which continues to benefit from, as well as inspire novel experimental studies.

N Heterocyclic Carbenes from the Author: Silvia D├şez-Gonz├ílez. Over the last fifteen years, N-heterocyclic carbenes (NHCs) have mostly been used as ancillary ligands for the preparation of transition metal-based catalysts. Compared to phosphorus-containing ligands, NHCs tend to bind more strongly to metal centres, avoiding the necessity for the use of excess ligand in catalytic reactions. The corresponding complexes are often less sensitive to air and moisture, and have proven remarkably resistant to oxidation. Recent developments in catalysis applications have been facilitated by the availability of carbenes stable enough to be bottled, particularly for their use as organocatalysts. This book shows how N-heterocyclic carbenes can be useful in various fields of chemistry and not merely laboratory curiosities or simple phosphine mimics. NHCs are best known for their contribution to ruthenium and palladium-catalysed reactions but the scope of this book is much broader. The synthesis of NHC ligands and their corresponding metal complexes are covered in depth. Moreover, the biological activity of NHC-containing complexes, as well as an overview of their theoretical aspects are included. Such metal species are further examined, not only in terms of their catalytic applications, but also of their stereoelectronic parameters and reactivity/stability. Finally, special attention is given to the hot topic of organocatalysis. The book will be of interest to postgraduates, academic researchers and those working in industry.

Investigations Of Organometallic Reaction Mechanisms Using Ultrafast Time Resolved Infrared Spectroscopy from the Author: Justin Lomont. Ultrafast time-resolved infrared spectroscopy provides a powerful tool for studying the photochemistry of organometallic complexes. The studies described herein focus on the mechanisms of photochemically initiated organometallic reactions with a particular emphasis on two topics: the role of spin states and spin state changes in organometallic reactions, and the primary photochemical dynamics of complexes containing metal-metal bonds (e.g. transition metal dimers and clusters). Many of these studies seek to uncover trends in reactivity based on the spin states of organometallic reaction intermediates, with the goal of being able to offer some level of predictive insight into the reactivity of complexes as classified by their spin multiplicity. The reactivity of various coordinatively unsaturated reaction intermediates are studied with respect to bond activation, electron transfer, excited state photoisomerization, and other classes of reactions important to organometallic catalysis. A second focus, which shares some degree of overlap with the topic of spin state changes, is the primary photochemistry of complexes containing metal-metal bonds. Several of the studies reported herein use time-resolved infrared spectroscopy to examine the primary photochemical processes occurring upon excitation of transition metal dimers and clusters, and often spin state changes also found to play an important role. Results of computational chemistry calculations are frequently used to facilitate interpretation of the experimental results by computation of structures, relative energies, infrared spectra, and spin-orbit coupling for the complexes studied experimentally. Additional studies outside these two primary areas of focus also investigated the ring-slippage of cyclopentadienyl ligands and the CO-delivery properties of a popular CO-Releasing Molecule.
