Lomonosov Moscow State University, Moscow , USSR Preface The first volume of Advances in Organometallic Chemistry was published early in 1964, and twelve other volumes have appeared since that date. The Editors have sought to produce a series of books containing specialist articles on all aspects of this field. The success of the series, as judged by the reviews of the books published in the journal literature, is due in large measure to the cooperation and help we have received from some one hundred and ten contributors. However, the demand for authoritative surveys of topics in organometallic chemistry derives mainly from the continued resilience of this area of endeavor, one measure of which is the annual appearance of over 2000 primary journal articles. After a little over a decade of publication it seemed to the Editors that we should arrange for the appearance of a commemorative Volume con- taining articles by distinguished chemists which would emphasize both the wide scope of organometallic chemistry and its international character. The number of contributors was necessarily limited by the need to keep the book to a reasonable length. This presented a problem in relation to selection of authors. Our choice is, therefore, a personal one guided to some degree by geographical distribution and the desire to balance transition metal chemistry versus main group metal chemistry. F. G. A. STONE It.
