Transfer hydrogenation of alkynes using HCO2HâNEt3 as a hydrogen donor in the presence of Pd0-catalyst proceeds highly stereoselecively to afford cis-alkenes in excellent yields, thus providing a practical method for conversion of alkynes to cis-alkenes.
在Pd0催化剂存在下,使用HCO2H-NEt3作为氢供体,
炔烃的氢转移反应具有高度立体选择性,能够以极高的产率生成顺式烯烃,从而为
炔烃转化为顺式烯烃提供了一种实用的方法。
