オレフィンのメタセシス

抄録

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 :
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.
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.
3. Some recent aspects of the stereochemical selectivity in the olefin metathesis reaction are also discussed in terms of the carbene complex mechanism.
