Book Description
Although organotransition metal chemistry has been developing rapidly over the past 20 years, it is only recently that applications of transition metal complexes to organic synthesis have started to be exploited. This unique book provides an introduction to organometallic chemistry for chemists who have little or no experience in the field, describes the work that has already been done using organotransition metal complexes for synthesis, and indicates to organic and organometallic chemists the type of synthetic problems that can be solved using organometallic compounds. It covers all major advances that have been made in this rapidly expanding area of chemistry, including not only reactions that already have well established applications for synthesis but also many recently discovered potentially useful reactions, providing a survey of recent literature.

Book Description
Explore the latest advances involving organo/metal combined catalysts from leading contributors in the field In Asymmetric Organo-Metal Catalysis: Concepts, Principles, and Applications, accomplished chemist Liu-Zhu Gong delivers a comprehensive discussion of how to design efficient organo/metal combined catalyst systems, new cooperatively catalyzed asymmetric reactions, relay catalytic cascades, and multicomponent reactions. The distinguished author covers critical topics, like the combined catalysis of chiral phase transfer catalysts, enamine, iminium, nucleophilic Lewis base, or Bronsted acids with metal complexes, while also covering the cooperative catalysis of photocatalysts and organocatalysts. The book offers readers an exploration of the general concepts and principles of bond activation and reorganization, together with a comprehensive introduction to the historical developments and recent advances in the field. Readers will also benefit from the descriptions of new chemistry and new synthetic methods included within. Asymmetric Organo-Metal Catalysis also provides: Thorough introductions to chiral PTC-metal cooperative catalysis and enamine-metal cooperative catalysis Comprehensive explorations of iminum-metal relay catalysis and cooperative catalysis of bronsted acids and transition metals Practical discussions of metal-bronsted acid relay catalysis and Lewis base–Lewis acid cooperative catalysis In-depth examinations of Lewis base-transition metal cooperative catalysis and photocatalysis combined with organocatalysis Perfect for organic, catalytic, and pharmaceutical chemists, Asymmetric Organo-Metal Catalysis: Concepts, Principles, and Applications is also an invaluable resource for chemists working with or on organometallics.

Book Description
The demand for selective organic reactions is growing more acute everyday. Indeed, greater product selectivity has an important impact on energy and resource utilization, in terms of reduced process energy requirements for product separation and purification, in terms of low-value by-products, and in terms of environmental acceptance and compatibility. Moreover, more and more chemicals, especially pharmaceuticals, have to be sold in an optically active form. The search for selectivity constitutes a tremendous challenge for the chemists. In the last two decades, homogeneous transition metal based catalysis has emerged as one of the most promising tools for obtaining selectivity. In connection with developments in this area, this book contains updated and expanded versions of most of the lectures presented at a Cornett course held in Trieste (Italy) in 1989 and sponsored by the European Community. A primary aim is to cultivate a deeper understanding of the parameters that govern the selectivities and stimulate a wider utilization of transition metal based catalysis in organic synthesis. All aspects of selectivity, chemo-, regio-, stereo- and enantioselectivity are considered and illustrated by applications in various fields or organic synthesis. The impact of catalysis in oxydation, reduction, carbonylation reactions, carbene chemistry, in Ni and Pd promoted dimerizations, oligomerizations as well as fonctionalisations is stressed, quite often with special emphasis laid on reaction mechanisms. In this aspect, the last chapter examplifies the interest of high pressure NMR and IR when investigating the nature of reaction intermediates in homogeneous reactions.

Book Description
Metallocene is a well known sandwich complex with two cyclopentadienyl ligands such as ferrocene. Recently, such metallocene compounds have been found to be very characteristic and they have become very important, not only in the area of organic synthesis, but also in polymerization in industry. Metal complexes with one cyclopentadienyl ligand have also become popular as half sandwich complexes. The number of researchers in the field of metallocenes has increased rapidly. However, the origin of the characteristic reactivity of metallocenes is not fully understood. In this volume, the chemistry of metal complexes with at least one cyclopentadienyl ligand is comprehensively covered by leading experts. Reactions discussed here are (i) natural product synthesis, (ii) catalytic asymmetric synthesis, (iii) cyclization reactions, (iv)catalytic reactions, (iv) polymerization reactions and (v) carbon-carbon bond cleavage reactions. The reader will have access to useful information about the current state of metallocene chemistry.

Book Description
Organo-Transition Metal Compounds and Related Aspects of Homogeneous Catalysis covers compounds that possess carbon atoms bonded to metal and to other carbon atoms. The order in which the substances appear in the book is based on the number of carbon atoms it have. The first section is about the alkyl, aryl, ethynyl, acyl, and carbene complexes. The second section deals with olefin and chelating diolefin complexes and complexes formed from acetylene. The following section covers the p-allylic complexes. The structures, stability, and bonding of alkyl and aryl complexes are fully covered. The magnetic moments and electronic spectra are discussed in detail.The fourth section discusses the conjugated diolefinic complexes that contain butadiene or cyclobutadiene. The rest of the book focuses on cyclopentadienyls, arene complexes, tropylium complexes, and complexes formed from cyclo-octatetraene or azulene. The book will be a useful tool for chemists, chemical engineers, and students and researchers in the field of chemistry.

Book Description
Controlling the absolute stereochemistry of molecules is a major challenge to contemporary chemists. Achieving high enantioselectivity with catalytic amounts of a chirality transfer (or inducing) agent, and the ease of regenerating such catalysts is yet another challenge. Due to the involvement of various transition metal complexes, the relatively young field of enantioselective catalysis has emerged as a powerful tool for organic chemistry.

Book Description
Organotransition Metal Chemistry: A Mechanistic Approach describes a mechanistic approach to the study of the chemistry of organotransition metals. Organotransition metals are discussed in relation to their reactions with specific functional groups or types of compounds rather than by metals. Topics covered include the formation of hydrogen and carbon bonds to transition metals; reactions of transition metal d- and p-bonded derivatives; and addition and elimination reactions of olefinic compounds. This book is comprised of 10 chapters and begins with a historical overview of organotransition metal chemistry, together with the unique chemistry of transition metals and mechanisms of ligand replacements. The following chapters discuss the methods of preparation of hydrido complexes and carbon-transition metal bonds; homogeneous hydrogenation reactions; isomerization, dimerization, oligomerization, and polymerization of olefins; and reactions of dienes, trienes, and tetraenes with transition metal compounds. Transition metal reactions with acetylenes and carbon monoxide as well as organic carbonyl compounds are also examined. This monograph should be of value to organic chemists as well as students and researchers of organic chemistry.
