The series Topics in Organometallic Chemistry presents critical overviews of research results in organometallic chemistry. As our understanding of organometallic structure, properties and mechanisms increases, new ways are opened for the design of organometallic compounds and reactions tailored to the needs of such diverse areas as organic synthesis, medical research, biology and materials science. Thus the scope of coverage includes a broad range of topics in pure and applied organometallic chemistry, where new breakthroughs are being achieved that are of significance to a larger scientific audience. The individual volumes of Topics in Organometallic Chemistry are thematic. Review articles are generally invited by the volume editors.

A wide range of chemical products (especially fine chemicals) are important for a healthy and enjoyable modern life; therefore efficient syntheses of these materials are essential. Traditional stoichiometric processes need to be replaced by modern catalytical methods in the change to sustainable chemistry and the production of lower amounts of waste. This book summarizes the wide variety of catalytic methods that have been developed and applied on an industrial scale in recent years to fulfill this goal. The synthesis of compound classes such as pharmaceuticals, agrochemicals, flavoring, and fragrance compounds as well as food additives such as vitamins exemplify the use of these modern catalytic methods in the modern chemical industry.

Catalysts are increasingly used by chemists engaged in fine chemical synthesis within both industry and academia. Today, there exists a huge choice of high-tech catalysts, which add enormously to the repertoire of synthetic possibilities. However, catalysts are occasionally capricious, sometimes difficult to use and almost always require both skill and experience in order to achieve optimal results. This series aims to be a practical help for advanced undergraduate, graduate and postgraduate students, as well as experienced chemists in industry and academia working in organic and organometallic synthesis. The series features: * Tested and validated procedures. * Authoritative reviews on classes of catalysts. * Assessments of all types of catalysts. * Expertise from the Leverhulme Centre for Innovative Catalysis, Liverpool, UK. The review section in the first volume of the series contains a report by Stanley M. Roberts on the integration of biotransformations into the catalyst portfolio. The procedure section contains a wide variety of synthetic protocols, such as epoxidations of unsaturated ketones and esters, asymmetric reductions of carbon-oxygen double bonds, asymmetric hydrogenations of carbon-carbon double bonds and other types of reaction. The featured catalysts include a wide range of different materials such as poly-D-leucine, D-fructose-based dioxiranes, oxaborolidine borane, some important titanium and ruthenium complexes as well as baker's yeast. For each reaction there are one or several detailed protocols on how to prepare and employ the various catalysts.

Heterogeneous catalysis plays a major role in the organic synthesis of specialty and fine chemicals. However, as the interaction between surface sites and functional groups is complex, more investigations are necessary into the effects of catalysts on the reaction mechanisms. The Third International Symposium on Heterogeneous Catalysis and Fine Chemicals provided an opportunity for discussions on the basic and practical aspects of this subject between researchers, manufacturers and users of solid catalysts for synthesis of fine chemicals. The present volume comprises the invited plenary lectures and research papers classified under the three main headings, hydrogenation, oxidation and acid-catalysis. All papers were refereed. A large variety of reactions are described, the emphasis being on selectivity, taking into account all aspects: chemo-, regio-, and stereoselectivity (including enantioselectivity) and on the change of these selectivities as a function of the characteristics of the catalysts and operating conditions.

A comprehensive discussion of the theory, practice and application of catalytically active transition metal species and their application in the production of specialist polymeric materials. The material is presented in a progressive manner, suitable for non-experts and those seeking an introduction to the field. The bibliographies supplied are complete and up to date, making the book an indispensable guide to the primary literature for the more theoretical background to the topics discussed. After a comprehensive discussion of initiating systems for speciality chemical synthesis the book goes on to deal with a wide range of topics in materials science, including: alkenamers, polyacetylenes, industrial applications and liquid rocket engine fuels.

Focusing on preparation and applications in synthesis and catalysis, this book finally closes a gap in the literature by summarizing this hot topic for the first time. As such, it gathers in one volume the key features of metal vinylidene and allenylidene complexes as well as reactive species and covers applications in metathesis, polymerization, molecular materials, carbon rich compounds and fine chemical production. The emphasis here is on the selective transformations of alkynes and enynes plus simple and complex molecules containing a triple C-C bond. The result is a must-have ready reference for organic, catalytic, complex, theoretical and polymer chemists, as well as those working with/on organometallics.
