Copper-catalyzed α-C–H acyloxylation of carbonyl compounds with terminal alkynes†
Abstract
Herein, a copper/TBHP catalyst system for the α-C–H acyloxylation of carbonyl compounds is developed using terminal alkynes as the acyloxy source. A variety of carbonyl compounds and terminal alkynes are tolerated in this reaction. In addition, its possible mechanism is proposed.
