A highly selective synthesis of a variety of functionalized allylic 2-alkynoates was realized via the carboxylative coupling of terminal alkynes, allylic chlorides, and CO2 catalyzed by the N-heterocyclic carbene copper(I) complex (IPr)CuCl. The catalyst can be easily recovered without any loss in activity and product selectivity.
