PrefaceThis textbook is intended for undergraduate students starting organometallic chemistry and researchers who want to use organometallic compounds, but are not professionals in organometallic chemistry. Although there are already many textbooks of organometallic chemistry that are relatively self-contained, the lack of practical guidance in organometallic chemistry is a deterrent to the use of organometallic compounds by beginners and nonprofessionals Organometallic compounds are formed by nearly all metals and show a variety of structures and reactivities. Thus large compilations such as Comprehensive Organometallic Chemistry, Dictionary of Organometallic Compounds, Organometallic Synthesis, and Inorganic Synthesis have to be read to understand the chemistry of organometallic compounds as well as to learn synthetic methods, such books are inconvenient for these outsiders. A book that provides the most important references to organometallic compounds including practical prepara tion and chemistry would be useful not only in undergraduate or graduate school courses but also in the research laboratory. This book describes briefly the concepts of organometallic chemistry and provides an overview of the chemistry of each metal including the synthesis and handling of its important organometallic compounds. The idea of publishing this type of book in English originated from the Japanese book planned and published by Professors H. Suzuki and S. Komiya and editorially supervised by A. Yamamoto, which has been well received in our country. However this version is completely revised.

Parts of the book were edited and written during my stay at Indiana University and at the Australian National University. Particular thanks are due to Professor Kenneth G. Caulton and Professor Martin A. Bennett for brushing up our English and giving advice. I also thank Professor Akira Nakamura at Osaka University for giving me the opportunity to edit this book which has been entirely written by young Japanese organometallic chemists. Acknowledgment is also made to the excellent services of John Wiley & Sons Ltd for publishing the book. I also express my hearty gratitude to my good friend Professor Akira Miyashita at Saitama University for his great contribution to this book during the early stages. Unfortunately, owing to serious illness, he was unable to complete his contribution. Thus the enormous efforts, due to urgent preparation of manuscripts, by Professor Ito at Yokohama University and Professor Mashima at Osaka University are greatly acknowledged.

Finally, I would like to express my hearty thanks to my wife and family for their continuous help and encouragement.

Introduction: Organometallic chemistry needs no special ideas if general chemical concepts are accepted. Many organic chemists feel that metals, especially those of the transition series, have various types of bonding schemes with molecules, atoms and ligands, and that the valency of the metal may change arbitrarily. In fact, molecular compounds of transition metals have well-defined structures, such as octahedral, square planar, trigonal bipyramidal, etc, depending on the electronic state of the metal. On the other hand, organometallic compounds are generally believed to be very air-and-moisture sensitive, since very well known organometallic compounds such as alkyl lithiums and Grignard reagents are vigorously hydrolyzed in solution and organoaluminums are even flammable on exposing to air. Furthermore organotransition metal complexes are active intermediates in many catalyses. These facts probably make many researchers hesitate to use apparently unstable organometallic species in the laboratory. However in recent years, by virtue of the versatility of organometallic compounds in organic synthesis under mild conditions, many organic chemists are now using organometallic compounds as catalysts as well as reagents for creating new highly regio- and stereoselective reactions. Significant developments in these fields are now considered to be highly dependent on the organometallic reagents.

Organometallic chemistry is essentially based on coordination chemistry and organic chemistry. It is not too much to say that Werner's concept of coordination compounds began the development of coordination chemistry in the last 100 years, since it provided the basis for understanding complex inorganic compounds at a molecular level. However, inorganic and organic chemistries unfortunately tended to develop quite independently. Coordination chemists have concentrated on structure and bonding in relation to spectroscopy both experimentally and theoretically, whereas organic groups have used compounds containing metal carbon bonds as a tool of organic synthesis based on organic chemistry. As a result, inorganic chemists have provided very important structural and theoretical concepts relating to coordination compounds, though they still had resistance to handling air-sensitive organometallic compounds. Coordination chemists are now attempting to resolve problems both in solid state materials by building clusters and on the roles of metals in biology at a molecular level. On the other hand, many highly selective and efficient organic synthetic reactions and catalyses using transition and main-group metals are still developing and attracting growing interest. Selectivities in metal mediated organic reactions are now competing with those of enzymes. It is generally considered that, after the discovery of ferrocene


in 1951, organometallic chemistry has achieved explosive development. Organo. metallic chemists have helped to eliminate the barrier between organic and inorganic chemistry by dealing with all inorganic and organic compounds at a molecular level. As a result, the important concepts such as T-back bonding, agostic interaction, B. hydrogen elimination, reductive elimination, insertion, etc., have been introduced into the field of chemistry,

In recent years, scientists and chemists in fields other than organometallic chemistry have been frequently required, for their own purposes, to handle organometallic com. pounds which are believed to be very unstable and toxic. However, the problem is real. ly not so difficult if one knows the general techniques for handling under inert gases and in vacuum. General concepts in organometallic chemistry are also not unusual, if both organic and inorganic chemistries are treated together. The purpose of this text. book is to serve as a practical guide to understand the general concepts of organometallic chemistry and methods of handling unstable compounds for graduate and undergraduate students and scientists who are not specialists in organometallic chemistry.

This book is divided in two parts: general concepts and the chemistry of individual metals, including practical synthetic methods for representative organometallic compounds. Chapters 2 and 3 summarize important fundamentals in organometallic chemistry Chapter 4 describes experimental techniques, where the simplest ways to manipulate air-sensitive compounds are also included. Specialized techniques requr. ing expensive facilities are not mentioned in detail, since they have already been described in references. In Chapters 5-17, the general chemistry of individual metals is summarized with references. Half of each chapter includes practical methods for the synthesis of organometallic compounds, including experimental tricks, which are usually not found in books, although some of them are referred to the original references.
