The collection of contributions in this volume presents the most up-to-date findings in catalytic hydrogenation. The individual chapters have been written by 36 top specialists each of whom has achieved a remarkable depth of coverage when dealing with his particular topic. In addition to detailed treatment of the most recent problems connected with catalytic hydrogenations, the book also contains a number of previously unpublished results obtained either by the authors themselves or within the organizations to which they are affiliated.Because of its topical and original character, the book provides a wealth of information which will be invaluable not only to researchers and technicians dealing with hydrogenation, but also to all those concerned with homogeneous and heterogeneous catalysis, organic technology, petrochemistry and chemical engineering.

Prior to 1979, consideration of the problem of the carcinogenicity of the aromatic amine class of chemicals took place primarily in poster sessions and symposia of annual meetings of the American Association for Cancer Research and analogous international associations. In November 1979 the first meeting concerned with the aromatic amines was held in Rockville, Haryland under primary sponsorship of the National Cancer Institute. The proceedings from this meeting were published as Monograph 58 of the Journal of the National Cancel' Institute in 1981. The second meeting in this series, the Second International Conference on N-Substituted Aryl Compounds, was held in March/April of 1982 in Hot Springs, Arkansas. The National Cancer Institute and The National Center for Toxicological Research were the primary sponsors of this meeting. The proceedings were published as Volume 49 of the journal En-vil'onmental Health Perspectives in 1983. The third meeting in this series was held in April of 1987 at the Dearborn Hyatt in Dearborn, Michigan. The principal sponsor of this meeting was the Heyer L. Pre ntis Comprehensive Cancer Center of Metropolitan Detroit. The proceedings, Carcinogenic and Mutagenic Responses to Aromatic Amines and Nitroal'enes, were published in 1987 by Elsevier Press. The fourth meeting was held in Cleveland, Ohio, on July 15-19, 1989.

Homogeneous hydrogenation is one of the most thoroughly studied fields of homogeneous catalysis. The results of these studies have proved to be most important for an understanding of the underlying principles of the activation of small molecules by transition metal complexes. During the past three decades homogeneous hydrogenation has found widespread application in organic chemistry, including the production of important pharmaceuticals, especially where a sophisticated degree of selectivity is required. This volume presents a general account of the main principles and applications of homogeneous hydrogenation by transition metal complexes. Special attention is devoted to the mechanisms by which these processes occur, and the role of the recently discovered complexes of molecular hydrogen is described. Sources of hydrogen, other than H2, are also considered (transfer hydrogenation). The latest achievements in highly stereoselective hydrogenations have made possible many new applications in organic synthesis. These applications are documented by giving details of the reduction of important unsaturated substrates (alkenes, alkynes, aldehydes and ketones, nitrocompounds, etc.). Hydrogenation in biphasic and phase transfer catalyzed systems is also described. Finally, a discussion of the biochemical routes of H2 activation highlights the similarities and differences in performing hydrogenation in both natural and synthetic systems. For researchers working in the fields of homogeneous catalysis, especially in areas such as pharmaceuticals, plastics and fine chemicals.

Immobilization of chiral catalysts is an important tool for improving overall efficiency of catalytic processes. However, heterogeneous catalysts often suffer from decreased activities and supported but still homogeneous catalysts can help overcome this issue. This book covers the most important concepts of homogeneous supported catalysis with an emphasis on enantioselective processes. It describes the state-of-the-art and latest developments in each area whilst critically evaluating the strengths and weaknesses of this important method. The book encompasses ionically-tagged catalysts, supported organocatalysts, supported ionic liquid phases, catalysis using soluble polymers, catalytic dendrimers, fluorous catalysts, water soluble catalysts and non-covalent immobilization methods. Potential developments and ideas for the future are also highlighted. There is a growing demand for effective and recyclable catalysts so this book, covering all the important methods in the field of supported homogeneous catalysis, will appeal to many researchers in academia and industry.

Die wichtigsten und nützlichsten Methoden der modernen stereoselektiven Synthese sind in diesem Band zusammengefasst. Viele anschauliche Beispiele für die Darstellung von Wirkstoffen und Naturstoffen regen zur gezielten Abwandlung und Integration in eigene Synthesewege an. Dabei geht es den Autoren weniger darum, das Gebiet in seiner Gesamtheit darzustellen; vielmehr versuchen sie, die wirklich grundlegenden Ansätze auszuwählen, die jeder organische Synthesechemiker kennen und anwenden sollte.

Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Opens the door to the sustainable production of pharmaceuticals and fine chemicals Driven by both public demand and government regulations, pharmaceutical and fine chemical manufacturers are increasingly seeking to replace stoichiometric reagents used in synthetic transformations with catalytic routes in order to develop greener, safer, and more cost-effective chemical processes. This book supports the discovery, development, and implementation of new catalytic methodologies on a process scale, opening the door to the sustainable production of pharmaceuticals and fine chemicals. Pairing contributions from leading academic and industrial researchers, Sustainable Catalysis focuses on key areas that are particularly important for the fine chemical and pharmaceutical industries, including chemo-, bio-, and organo-catalytic approaches to C H, C N, and C C bond-forming reactions. Chapters include academic overviews of current innovations and industrial case studies at the process scale, providing new insights into green catalytic methodologies from proof-of-concept to their applications in the synthesis of target organic molecules. Sustainable Catalysis provides the foundation needed to develop sustainable green synthetic procedures, with coverage of such emerging topics as: Catalytic reduction of amides avoiding LiAlH4 or B2H6 Synthesis of chiral amines using transaminases Industrial applications of boric acid and boronic acid catalyzed direct amidation reactions C H activation of heteroaromatics Organocatalysis for asymmetric synthesis Offering a balanced perspective on current limitations, challenges, and solutions, Sustainable Catalysis is recommended for synthetic organic chemists seeking to develop new methodologies and for industrial chemists dedicated to large-scale process development.
