A simple highly versatile and efficient method has been developed for the three-component coupling of aldehydes, amines and alkynes to prepare propargylamines, in the presence of a catalytic amount of $BiCl_3$. The advantages of methods are high yield, mild reaction conditions, no environmental pollution and easy work up procedure.
一种简单、高度多功能且高效的方法已经被开发用于醛、胺和
炔烃的三组分偶联,以制备炔基胺,该过程在催化量的BiCl₃存在下进行。该方法的优点包括高产率、温和的反应条件、无环境污染和简单的后处理过程。
