摘要

The historical aspects and modern developments of the metathesis reaction are summarized.In particular,emphasis is made on the leading role of the mechanistic work and proposals by Yves Chauvin on the history of the efficient catalysts discoveries by the groups of R.R.Schrock and R.H.Grubbs.It is pointed out how the Chauvin metathesis mechanism with formation of metallacyclobutane has been generalized to many organometallic catalytic reactions that also involve square intermediates including a metal atom.The quest of efficient metathesis catalysts is a success story starting from organometallic mechanisms and syntheses that has now invaded the worlds of organic synthesis and polymer science.Indeed,the Schrock and Grubbs catalysts are particularly essential for green chemistry,since they considerably shorten organic syntheses and provide simple paths for novel ones.
