Opis

In 1990, the SFB (Sonderforschungsbereich) entitled "Selektive Reaktionen Metall-aktivierter Molekule" was established at the University of Wurzburg to promote efficient cooperation between various fields of chemistry and physics. An essential ingredient of this interdisciplinary research project is the periodic holding of meetings in order to present actual results and recent trends in organometallic chemistry and related areas. The third international symposium was held at the Chemical both from academia and industry. In plenary lectures provided by reputated invited scientists and posters contributed by the members of the SFB 347 a broad spectrum of actual results obtained in selective metal catalysis, organometallic synthesis, bioorganic reactions, physico-chemical and theoretical studies on organometallic compounds and intermediates has been covered. This volume presents a useful insight in the recent trends and will stimulate further progress in the field."
