Preface

In the 20 years since 'Principles' first appeared the field of organometallic

chemistry has continued to expand very rapidly. During the 1950s and 1960s the

main theme was the preparation and structural characterization of new

compounds, especially those ofthe transition elements. The last two decades ha ve

seen the development of this theme and many unexpected materials such as

carbyne complexes and cluster compounds have been discovered. There is now

increasing emphasis on the application of organometallics of al! types in organic

synthesis, both in the laboratory and on an industrial scale.

These developments, although very exciting, present problems to anyone rash

enough to attempt to write an undergraduate text. Such a book should not be too

long and should present a balanced view ofthe field without becoming completely

indigestible through a mass of detail. The excellent reference work, 'Comprehensive

Organometallic Chemistry', published in 1 9 8 2, consists of 8 tomes and a large

index volume. Unfortunately, as Professor Coates has' remarked, "though the

content of science has grown so much, it is unlikely that the effective capacity of

students' brains has increased substantially over the past 15-20 years."

It has therefore been necessary to be very selective in the topics discussed.

Emphasis is laid on structures, bonding, methods of preparation and general

reactions of organometallic compounds. An elementary knowledge of thermodynamics,

bonding theory and the use of spectroscopic methods of structure

determination is assumed. The Periodic Groups provide a logica! framework for

treating the compounds of the typical elements. In the area of the transition

elements, however, the chemistry has been classified in terms of the electron

number of the principal ligand. The alternative approach, classification by

reaction type, can have the disadvantage that examples have to be drawn from

otherwise unrelated areas, which can prove confusing to the beginner.

The relevance of organometallic chemistry to industry has been indicated

throughout. Thanks are duc to severa! firms including Associated Octel. Bayer

AG, British Petroleum pic, Dow Corning, Esso and Thomas Swan & Co. Ltd. for

providing information in this connection. A chapter describes studies of the

mechanisms of homogeneously catalysed reactions. A few of these reactions are

used in industry. In other cases such mechanistic studies help to clarify how the

related heterogeneous systems, which are used in practice, may work.
