ChemInform Abstract: Cobalt‐Catalyzed Hydroarylation of Alkynes Through Chelation‐Assisted C—H Bond Activation.

Abstract

Chelation‐controlled addition of arylpyridines or aromatic imines towards internal alkynes proceeds readily in the presence of a CoBr2—monophosphine catalyst to give tri‐substituted olefins with high regio‐ and stereoselectivities in most cases.
