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.
通过N-杂环卡宾铜(I)配合物(IPr)CuCl催化的末端炔烃,烯丙基氯化物和CO 2的羧基偶联,实现了多种官能化烯丙基2-链烷酸酯的高度选择性合成。可以容易地回收催化剂,而没有任何活性和产物选择性的损失。
