Catalytic skeletal reorganization of enynes through electrophilicactivation of alkynes: double cleavage of C–C double and triple bonds

Abstract

Skeletal reorganization of enynes was studied by electrophilicactivation of alkynes with various metal catalysts; the products obtained can be classified into two types, one involving carbon–carbon bond single cleavage (type I) and the other involving carbon–carbon bond double cleavage (type II). Summarized in this review are our studies of the catalytic skeletal reorganization of enynes through the electrophilicactivation of alkynes, and recent results from selective formation of type II products.
