Hydrogenation is one of the most useful, boared-scoped reactions available to the synthetic organic chemistry. The aim of this work is to give the reader ready access to what can be done with hydrogenation anв how to do it. Appropriate choise of catalyst, solvent, and reaction conditions are illustrated throughout, and where possible, the influence of these factors has been reduced tj wjrking generalities. This volume is heavily documented to support these generalities and to make often difficult to find literature readily available. It is hoped that the reader will find this a useful work.
