This review article treats the transition metal catalyzed metathesis of olefins which provides a useful method for synthesizing olefinic compounds. Contents of the present review are as follows : <BR>1. The applicability of the olefin metathesis to the synthesis of acyclic and cyclic olefins, acetylenes, cyclopropane derivatives, perfectly alternating copolymers, catenanes, and sex attractant hormones is mentioned.<BR>2. A general survey of the mechanistic considerations of the olefin metathesis is given. There is a growing consensus that the metal carbene and metallocyclobutane intermediates are involved in the reaction.<BR>3. Some recent aspects of the stereochemical selectivity in the olefin metathesis reaction are also discussed in terms of the carbene complex mechanism.
