Abstract

Palladium acetate was encapsulated onto highly ordered mesoporous silica MCM-41 with the aid of ionic liquid. The immobilized Pd complex can efficiently catalyze Heck coupling reactions of activated and non-activated aryl halides with acrylates. The Pd catalyst exhibited remarkably high catalytic activity and outstanding stability. Moreover, the immobilized palladium acetate could be recycled at least six times without significant loss of activity.

摘要

借助离子液体将醋酸钯封装到高度有序的介孔二氧化硅MCM-41上。固定化的钯配合物能够高效催化活性和非活性芳基卤化物与丙烯酸酯的Heck偶联反应。该钯催化剂表现出极高的催化活性和出色的稳定性。此外，固定化的醋酸钯可以循环使用至少六次而活性无明显损失。
