Abstract

A hydroalkynylation reaction of 1,3-dienes with simple alkynes, facilitated by an efficient nickel catalyst system with the 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (Xantphos) ligand, is presented. This reaction displays a broad substrate range for alkynes, encompassing both aryl alkynes and alkyl alkynes, thereby overcoming previous constraints in 1,3-diene hydroalkynylation. The method offers a convenient and direct means for obtaining allylic alkynes with high atom and step economy.
