Catalytic Hydrogenation in Organic Syntheses focuses on the process of catalytic hydrogenation in organic synthesis. This book gives the reader easy access to catalytic history, to show what can be done and how to do it. A variety of working generalities and common sense guides are given as aids in selecting catalytic metal, catalyst support, concentration of metal and catalyst, solvent, and reaction conditions. All manner of hydrogenation catalysts are considered and mechanisms of hydrogenation are presented at a level that is useful to the synthetic organic chemist. This volume is comprised of 15 chapters and begins with an overview of catalytic hydrogenation and heterogeneous hydrogenation catalysts, along with hydrogenation reactors and reaction conditions. The discussion then shifts to the hydrogenation of compounds such as acetylenes, olefins, aldehydes, ketones, nitriles, oximes, acids, esters, lactones, anhydrides, and nitro compounds as well as carbocyclic aromatics and heterocyclic compounds. The reader is also introduced to reductive alkylation, catalytic dehydrohalogenation, and hydrogenolysis of small rings. A chapter on miscellaneous hydrogenolyses concludes the book. This book will be of interest to organic chemists working in the field of catalytic hydrogenation.

Catalysis in Organic Syntheses contains the proceedings of the Seventh Conference on Catalysis in Organic Syntheses held in Chicago, 5-7 June 1978. The conference was sponsored by The Organic Reactions Catalysis Society, an affiliate of The Catalysis Society. Most of the papers reflect the main interest of the Society membership, namely, the application of catalysis as a tool for the synthetic organic chemist rather than studies of catalytic phenomena per se, the latter subject being amply covered in other symposia. It is not surprising then that the largest group of papers deal with catalytic hydrogenation, the catalytic reaction most often encountered in organic synthesis. Other subjects in the burgeoning field of catalysis are not neglected however, as evidenced by papers on the spectroscopic evaluation of catalysts, homogenous catalysis by organometallic complexes, and the catalysis of coal conversion. Finally a group of papers explore some safety considerations in performing catalytic transformations.

A reactions oriented course is a staple of most graduate organic programs, and synthesis is taught either as a part of that course or as a special topic. Ideally, the incoming student is an organic major, who has a good working knowledge of basic reactions, stereochemistry and conformational principles. In fact, however, many (often most) of the students in a first year graduate level organic course have deficiencies in their undergraduate work, are not organic majors and are not synthetically inclined. To save students much time catching up this text provides a reliable and readily available source for background material that will enable all graduate students to reach the same high level of proficiency in organic chemistry. Produced over many years with extensive feedback from students taking an organic chemistry course this book provides a reaction based approach. The first two chapters provide an introduction to functional groups; these are followed by chapters reviewing basic organic transformations (e.g. oxidation, reduction). The book then looks at carbon-carbon bond formation reactions and ways to ‘disconnect’ a bigger molecule into simpler building blocks. Most chapters include an extensive list of questions to test the reader’s understanding. There is also a new chapter outlining full retrosynthetic analyses of complex molecules which highlights common problems made by scientists. The book is intended for graduate and postgraduate students, scientific researchers in chemistry New publisher, new edition; extensively updated and corrected Over 950 new references with more than 6100 references in total Over 600 new reactions and figures replaced or updated Over 300 new homework problems from the current literature to provide nearly 800 problems to test reader understanding of the key principles
