摘要/Abstract

摘要： 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。

Abstract: Polystyrene-divinylbenzene(4%) beads were combined with anhydrous aluminium chloride and stannic chloride (1:1) in chloroform to form a stable complex containing 7.73% of chlorine, in which the ratio of metal aluminium to metal tin is 2/1. It correspond to (0.278 mmol SnCl₄+ 0.557mmol AlCl₃)/1g complex beads. The complex beads (PS-Al/Sn) can be used to catalyze a lot of organic reactions, such as esierifications, acetalizations, ketal formations, ethe-rification and the Friedel-Crafts alkylations. The greater reactivity of the PS-Al/Sn compared to PS-A1Cl₃(6) and PS-SnCl₄(7) was confirmed in these reactions. It is important that the dibasic metal complex PS-Al/Sn as a fine catalyst can be reused at least 10 times in high yields.
