In recent years its application to aspects of catalysis and metathesis has gained considerable interest from inorganic as well as organic chemists. In addition, organic synthesis by means of metal carbon multiple bond reagents offers the most sophisticated technology currently available. In consideration of these developments some of Professor E. O. Fischer's former coworkers and colleagues felt obliged to orga­ nize this NATO Advanced Research Workshop on Transition Metal Carbyne Complexes in the Bavarian Alps. They have been encouraged by the fact that most of the distinguished scientists in the field of metal-carbon multiple bond chemistry had finally agreed to participate and to present stimulating lectures. The organizers of the workshop are deeply grateful to the Scientific Affairs Division of the NATO for the generous financial support of the meeting in Wildbad Kreuth and for the preparation of this book. They also feel indebted to acknowledge the generous support from Wacker-Chemie, BASF, Peroxid-Chemie, Hoechst and Bayer. Finally they thank the staff of the Hanns-Seidel-Stiftung in Wildbad Kreuth for providing a pleasant and stimu­ lating atmosphere during the meeting. Fritz R. KreiBl Technische Universitat Miinchen ix Foreword It is not easy these days to put a focus on the rapid development of the chemistry related to metal-carbene and metal-carbyne complexes. This area of scientific research and tech­ nology has become so broad in scope and so high in knowledge that it is necessary to apply this focus by means of scientific meetings. The NATO Series of scientific conferences - another pieceful way of spending public money out of the defense budget - have greatly added to the development of high-techno­ logy research areas during the past decades. Organometallic chemistry has developed on this time-scale and has received great benefit from programmes like the NATO Series. Modelled after the success of a previous meeting on "Metal-Carbene Complexes", Professor KreiBl organized the consecutive conference on "Metal-Carbyne Complexes" nearby the cradle of these versatile, successful, chemically as well as industrially useful species: At Technische Universitlit Milnchen, Professor Ernst Otto Fischer was holding the chair of Inorganic Chemistry over a period of twenty years - from 1964 (following Walter Hieber) until 1984. Ernst Otto Fischer is one of the pioneers of organometallic chemistry. In Europe, he and Franz Hein, Karl Ziegler, Walter Hieber, Geoffrey Wilkinson, and Georg Wittig made the most eminent personal contributions to this highly interdisciplinary field of research. These days, catalysis, organic synthesis and materials science are the major areas of appli­ cation, with the latter segment being in rapid expansion. The basis of all these appli­ cations, however, remains to be synthesis and structure. Professor Fischer has mastered both areas ever since he entered the exciting field of organometallic chemistry through ferrocene (structure) and dibenzene chromium (synthesis). In later years he succeeded to synthesize the first organometallic compound exhibiting a metal-to-carbon triple bond - predominantly a result of great and long-lasting enthusiasm. Boron trihalides were thought to substitute a halogen atom for the alkoxy group in one of Fischer's metal carbene com­ pounds of general composition (CO)SM=C(OR')R (M = Cr, Mo, W). Quite unexpectedly in those days, the first carbyne complex resulted when my fellow-student Gerhard Kreis, now a chemist at Wacker-Chemie GmbH (Burghausen/Bavaria), performed the very experiments with utmost precision typical of him. The puzzling but xi xii correct elemental analysis of his new product, (CO)4ClW=C(Cc5Hs), performed by Manfred Barth in our institute is shown in Fig. 1.
