Coordination chemistry, as we know it today, has been shaped by major figures from the past, one of whom was Joseph Chatt. Beginning with a description of Chatt's career presented by co-workers, contemporaries and students, this fascinating book then goes on to show how many of today's leading practitioners in the field, working in such diverse areas as phosphines, hydrogen complexes, transition metal complexes and nitrogen fixation, have been influenced by Chatt. The reader is then brought right up-to-date with the inclusion of some of the latest research on these topics, all of which serves to underline Chatt's continuing legacy. Intended as a permanent record of Chatt's life, work and influence, this book will be of interest to lecturers, graduate students, researchers and science historians.

Hydrotreating catalysis with transition metal sulphides is one of the most important areas of industrial heterogeneous catalysis. The present book deals with the chemical and catalytic aspects of transition metal sulphides, focusing on their use in hydrotreating catalysis. The book¿s 12 chapters present reviews of solid-state, coordination and organometallic chemistry, surface science and spectroscopic studies, quantum chemical calculations, catalytic studies with model and real catalysts, as well as refinery processes. A presentation of state-of-the-art background to pertinent work in the field. Can be used as an introduction to the chemical and catalytic properties of transition metal sulphides as well as an advanced level reference.

The authors of this fourth volume in the series have reviewed the making and breaking of chemical bonds in a sophisticated manner. In particular, new pressures brought about by environmental concerns, larger demands for the medical and pharmaceutical sectors and economics of the market place are forcing us into demanding greater stereochemical control and better product yields for chemical reactions capable of producing useful products. The chapters are written by leading experts in this area and give excellent overviews of the strengths and weaknesses of the various methodologies. In Chapter 1 newer discoveries in such tried and true methods of C-C bond formation as alkylations and aldol reactions of metal enolates are reviewed. The author of Chapter 2 discusses the ability of ab-initio methods to justify the results of empirical observations in the field of transition metal derivatives of small molecules such as N2, CO2 and similar small molecules. Having established the strengths and weaknesses of the various approaches to such theoretical calculations, a more interesting approach to these methods is pursued, namely, their ability to predict, in those areas in which they are particularly strong and reliable, chemical and stereochemical events and/or results in advance of experiments, later carried out in the laboratory. Finally, Chapter 3 reviews the stereochemical results of electron transfer reactions in mononuclear copper compounds.

This book has been conceived to collect the most important recent advances in all areas of hydride chemistry research, including chemical reactivity, instrumental investigation, theory, and applications in the areas of catalysis, biochemistry and materials science. Many of the chapters have been written by the plenary lecturers of the EURO-Hydrides 2000 conference, but other leading scientists in this field have also been invited to contribute. The first part of the book focuses on the chemistry and catalysis of transition metal hydrides. Another block of chapters illustrates the most recent advances in the application of instrumental techniques to the study of the properties and reactivity of hydride compounds. The final part of the book illustrates the relevance of metal-hydrogen bonds in biochemistry and materials science. All of the chapters of this book have been evaluated by independent reviewers.
