聚苯乙烯交联白球在氯仿中与三氯化铝和四氯化锡等摩尔混合物反应,制成了一种相当稳定的高分子载体双金属系Lewis酸复合物。该复合物对酯化、缩醛、缩酮、成醚等有机反应具有良好的催化效能,并可重复使用多次。
Polystyrene cross-linked white balls reacted with aluminum chloride and stannic chloride in an equimolar mixture in chloroform to form a relatively stable polymeric bimetallic Lewis acid complex. The complex has good catalytic performance for esterification, acetal, ketal, ether and other organic reactions, and can be reused many times.
