Hydrosilylation

For fifty years, Hydrosilylation has been one of the most fundamental and elegant methods for the laboratory and industrial synthesis of organosilicon and silicon related compounds. Despite the intensive research and continued interest generated by organosilicon compounds, no comprehensive book incorporating its various aspects has been published this century. The aim of this book is to comprehensively review the advances of hydrosilylation processes since 1990. The survey of the literature published over the last two decades enables the authors to discuss the most recent aspects of hydrosilylation advances (catalytic and synthetic) and to elucidate the reaction mechanism for the given catalyst used and the reaction utilization. New catalytic pathways under optimum conditions necessary for efficient synthesis of organosilicon compounds are presented. This monograph shows the extensive development in the application of hydrosilylation in organic and asymmetric syntheses and in polymer and material science.

This volume describes the latest advances and perspectives in hydrosilylation, with a focus on new organometallic catalysts and their mechanistic aspects. Hydrosilylation is the reaction of ≡SiH with carbon-carbon, carbon-heteroatom or heteroatom-heteroatom bonds and is the most fundamental and elegant method for laboratory and industrial synthesis of organosilicon molecular and macromolecular compounds. Yet these reactions do require a catalyst, for which initially homogeneous noble metal catalyst, mainly platinum, rhodium, iridium or ruthenium were used. However the high prices, metallic residues of these valuable catalysts as well as issues with product purification, did increase the interest in developing new catalysts. Noteworthy in this regard are the recently developed hydrosilylation reactions using catalysts based on earth-abundant transition metals (for example Mn, Fe, Co, Ni) and heterogeneous catalysts presented here. This volume of Topics in Organometallic Chemistry is written for scientists interested in silicon chemistry and its catalytic aspects, but can also be used as valuable handbook for postgraduate and advanced undergraduate students working with organometallic chemistry, catalysis as well as synthesis of fine chemicals.

This handbook provides an up-to-date account of hydrosilylation reactions and the directions in which synthetic and mechanistic studies as well as practical applications of these processes are proceeding. The book consists of two parts: the first is descriptive, presenting the catalytic, mechanistic, structural and synthetic aspects of hydrosilylation, as well as its application in organic and organosilicon chemistry. The second part, presented in tabular form sets out encyclopedic information concerning reaction conditions taken from more than 2000 papers and patents in the period 1965 - 1990.

Catalysts are now widely used in both laboratory and industrial-scale chemistry. Indeed, it is hard to find any complex synthesis or industrial process that does not, at some stage, utilize a catalytic reaction. The development of homogeneous transition metal catalysts on the laboratory scale has demonstrated that these systems can be far superior to the equivalent heterogeneous systems, at least in terms of selectivity. is an increasing interest in this field of research from both an Thus, there academic and industrial point of view. In connection with the rapid developments in this area, four universities from the E.E.C (Aachen, FRG; Liege, Belgium; Milan, Italy; and Lille, France) have collaborated to organise a series of seminars for high-level students and researchers. These meetings have been sponsored by the Commission of the E.E.C and state organizations. The most recent of these meetings was held in Lille in September 1985 and this book contains updated and expanded presentations of most of the lectures given there. These lectures are concerned with the field of homogeneous transition metal catalysis and its application to the synthesis of organic intermediates and fine chemicals from an academic and industrial viewpoint. The continuing petroleum crisis which began in the early 1970s has given rise to the need to develop new feedstocks for the chemical industry.

Provides the background, tools, and models required to understand organic synthesis and plan chemical reactions more efficiently Knowledge of physical chemistry is essential for achieving successful chemical reactions in organic chemistry. Chemists must be competent in a range of areas to understand organic synthesis. Organic Chemistry provides the methods, models, and tools necessary to fully comprehend organic reactions. Written by two internationally recognized experts in the field, this much-needed textbook fills a gap in current literature on physical organic chemistry. Rigorous yet straightforward chapters first examine chemical equilibria, thermodynamics, reaction rates and mechanisms, and molecular orbital theory, providing readers with a strong foundation in physical organic chemistry. Subsequent chapters demonstrate various reactions involving organic, organometallic, and biochemical reactants and catalysts. Throughout the text, numerous questions and exercises, over 800 in total, help readers strengthen their comprehension of the subject and highlight key points of learning. The companion Organic Chemistry Workbook contains complete references and answers to every question in this text. A much-needed resource for students and working chemists alike, this text: -Presents models that establish if a reaction is possible, estimate how long it will take, and determine its properties -Describes reactions with broad practical value in synthesis and biology, such as C-C-coupling reactions, pericyclic reactions, and catalytic reactions -Enables readers to plan chemical reactions more efficiently -Features clear illustrations, figures, and tables -With a Foreword by Nobel Prize Laureate Robert H. Grubbs Organic Chemistry: Theory, Reactivity, and Mechanisms in Modern Synthesis is an ideal textbook for students and instructors of chemistry, and a valuable work of reference for organic chemists, physical chemists, and chemical engineers.

This volume contains 37 chapters on methods for reducing functional groups, organized into four main parts. (i) Reduction of C=X systems, where X is an electronegative heteroatom, divided into 14 chapters based on the degree of reduction, the oxidation level of the C=X substrate, and on the nature of the reagent. (ii) Reduction of X=Y systems, divided into three chapters, covering the reduction of such groups as nitro, azo, and the various kinds of P=O and S=O groups. (iii) Reduction of C=C and C≡C, divided into 12 chapters based on the method of reduction, with aromatic, heteroaromatic, and conjugated systems treated separately, and including an extensive discussion of hydrometallation. (iv) Reduction of single bonds, C-X to C-H, in eight chapters, including the hydrogenolysis of the various kinds of C-X bonds, the reduction of epoxides, and the reduction of vinyl derivatives to alkenes. Each chapter includes a discussion of chemoselectivity, regioselectivity, and stereoselectivity, wherever it is appropriate, and most include advice on the reagent of choice, and the mechanistic basis of the various methods of reduction. In short, it is, within the space available, as near to a comprehensive account of reduction in organic chemistry as one could hope for.
