Directed alkynylation of unactivated C(sp3)–H bonds with ethynylbenziodoxolones mediated by DTBP

Author affiliations

Abstract

A general and efficient method for the direct alkynylation of unactivated C(sp3)–H bonds under metal-free conditions is described. The reaction performs smoothly under mild conditions and shows excellent functional-group tolerance. Initial mechanistic investigation indicates that the reaction may involve a radical pathway.
