Organometallic Mechanisms And Catalysis

Organometallic Mechanisms and Catalysis: The Role of Reactive Intermediates in Organic Processes covers the mechanistic delineation of organometallic chemistry and catalysis. This book is organized into three parts encompassing 18 chapters. The first part describes first the oxidation-reduction process of organometals, followed by discussions on the catalytic reactions of peroxides, metal-catalyzed addition to olefins, and reduction of organic halides. This part also explores other reactions involving transition metal carbonyls and metal-catalyzed reactions of aromatic diazonium salts. The second part deals with some chemical aspects of organometals, such as their stability, thermochemistry, decomposition, hemolytic pathways, and the formation of carbon-carbon bonds. The third part examines the charge transfer processes and interactions of organometals with electron acceptors. This part further looks into the cleavage and insertion reactions of organometals with electrophiles, as well as the electrophilic and electron transfer mechanisms of organometals. Organic and inorganic chemists, teachers, and students will greatly benefit from this book.

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.

Vor allem an Studenten fortgeschrittener Semester und Doktoranden gerichtet ist dieses Lehrbuch der Katalyse mit metallorganischen Verbindungen, das auch biologisch relevanten Reaktionen viel Platz einräumt. Hervorragend zum Selbststudium geeignet - mit zahlreichen Übungsaufgaben, nach Schwierigkeitsgraden geordnet und durch Lösungen ergänzt.

Computational Methods in Organometallic Catalysis Discover recent advances in the mechanistic study of organometallic catalysis In Computational Methods in Organometallic Catalysis: From Elementary Reactions to Mechanisms, distinguished chemist and author Yu Lan delivers a synthesis of the use of calculation methods and experimental techniques to improve the efficiency of reaction and yield of product and to uncover the factors that control the selectivity of product. Providing not only a theoretical overview of organometallic catalysis, the book also describes computational studies for the mechanism of transition-metal-assisted reactions. You’ll learn about Ni-, Pd-, Pt-, Co-, Rh-, Ir-, Fe-, Ru-, Mn-, Cu-, Ag-, and Au- catalysis. You’ll also discover many of the experimental and theoretical advances in organometallic catalysis reported in the recent literature. The book summarizes and generalizes the advances made in the mechanistic study of organometallic catalysis. Readers will also benefit from the inclusion of: A thorough introduction to computational organometallic chemistry, including a brief history of the discipline and the use of computational tools to study the mechanism of organometallic chemistry An exploration of computational methods in organometallic chemistry, including density functional theory methods and basis sets and their application in mechanism studies A practical discussion of elementary reactions in organometallic chemistry, including coordination and dissociation, oxidative addition, reductive elimination, insertion, elimination, transmetallation, and metathesis A concise treatment of the theoretical study of transition-metal catalysis. Perfect for organic, catalytic, complex, and structural chemists, Computational Methods in Organometallic Catalysis will also earn a place in the libraries of theoretical chemists seeking a one-stop organometallic catalysis resource with a focus on the mechanism of transition-metal-assisted reactions.

This volume covers both basic and advanced aspects of organometallic chemistry of all metals and catalysis. In order to present a comprehensive view of the subject, it provides broad coverage of organometallic chemistry itself. The catalysis section includes the challenging activation and fictionalization of the main classes of hydrocarbons and the industrially crucial heterogeneous catalysis. Summaries and exercises are provides at the end of each chapter, and the answers to these exercises can be found at the back of the book. Beginners in inorganic, organic and organometallic chemistry, as well as advanced scholars and chemists from academia and industry will find much value in this title.

A succinct review of the essential concepts of organometallic chemistry, enriched throughout with examples that demonstrate how our understanding of organometallic chemistry has led to new applications in research and industry - not least in relation to catalysis.

Surface organometallic chemistry is a new field bringing together researchers from organometallic, inorganic, and surface chemistry and catalysis. Topics ranging from reaction mechanisms to catalyst preparation are considered from a molecular basis, according to which the "active site" on a catalyst surface has a supra-molecular character. This. the first book on the subject, is the outcome of a NATO Workshop held in Le Rouret. France, in May. 1986. It is our hope that the following chapters and the concluding summary of recommendations for research may help to provide a definition of surface organometallic chemistry. Besides catalysis. the central theme of the Workshop, four main topics are considered: 1) Reactions of organometallics with surfaces of metal oxides, metals. and zeolites; 2) Molecular models of surfaces, metal oxides, and metals; 3) Molecular approaches to the mechanisms of surface reactions; 4) Synthesis and modification of zeolites and related microporous solids. Most surface organometallic chemistry has been carried out on amorphous high-surf ace-area metal oxides such as silica. alumina. magnesia, and titania. The first chapter. contributed by KNOZINGER. gives a short summary of the structure and reactivity of metal oxide surfaces. Most of our understanding of these surfaces is based on acid base and redox chemistry; this chemistry has developed from X-ray and spectroscopic data, and much has been inferred from the structures and reactivities of adsorbed organic probe molecules. There are major opportunities for extending this understanding by use of well-defined (single crystal) oxide surfaces and organometallic probe molecules.

This volume presents the latest developments in the use of organometallic catalysis for the formation of bulk chemicals and the production of energy, via green processes including efficient utilization of waste feedstocks from industry. The chemistry of carbon dioxide relating to its hydrogenation into methanol –an eco-friendly energy storage strategy– and its uses as C1 synthon for the formation of important building-blocks for fine chemicals industry are covered. Catalytic hydrogenations of various functional groups and hydrogen transfer reactions including the use of first row metal catalysts are presented as well as the conversion of alcohols to carboxylates via hydrogen transfer with a zero-waste strategy using water. Transformation of renewable or bio-based raw materials is surveyed through alkene metathesis and C–O bond activations and functionalizations. A green aspect for selective formation of C-C, C-O and C-N bonds involves direct regioselective C–H bond activations and functionalizations. These transformations can now be promoted under mild reaction conditions due to the use photoredox catalyts. C–H bond oxidation using visible light leads mainly to the formation of C–O and C–N bonds, whereas cross-coupled C–C bonds can be formed through the radical additions on (hetero) arenes using photoredox assisted mechanism.
