Thus Volume XI11 had a strong flavor of metal-metal bonded compounds and Volume XIV contains a remarkably fine collection of solid-state syntheses. The present volume is no exception. It contains syntheses of many transition-metal compounds important in homogeneous catalysis, especially complexes of olefins, hydrogen, and nitrogen, which have interested me and my colleagues. However, I hope and believe that this volume also has general interest and that the techniques described will have broad application in inorganic chemistry. One of the strengths of INORGANIC SYNTHESES is the diversity of interests among the members of the Editorial Board. Their help in assembling preparations of all sorts of inorganic compounds prevents a volume from ever becoming a collection for just the practitioners of one narrow specialty. Perhaps the greatest strength of INORGANIC SYNTHESES is the support that it has received from inorganic chemists generally. Assembling this volume has done much to restore my faith in human nature. People have been immensely helpful in soliciting, contribut- ing, checking, and editing syntheses. At the risk of slighting individ- uals by omission, I am especially indebted to Charles Van Dyke for his initiative in assembling the chapter on germanium hydride derivatives and to George Ryschkewitsch and Roland Koster for contributing the two groups of syntheses that make up most of the chapter on boron compounds.
