Redox induced reactions of transition metal vinylidene and related complexes

摘要

In this review redox induced reactions of transition metal vinylidene complexes have been summarized for the first time. Surprisingly there are no reports on metal-centered reactivity of redox-activated vinylidenes so that the prior emphasis is made on ligand-centered reactions (C_β—C_β dimerizations, cleavage, and formation of C_β—H bonds etc.). A discussion of redox activation of related transition metal σ-alkynyl and alkylidyne complexes is limited by the cases wherein transition metal vinylidenes are formed at least as intermediates.
