| 摘 要： | 硫酸亚铈作为一种便宜的和有效的催化剂催化芳香化合物与苄基醇、烯丙醇类化合物和苄基氯的傅-克烷基化反应. 在1～10 mol%的硫酸亚铈存在下, 芳香化合物分别与苄基醇、烯丙醇类化合物和苄基氯能够顺利有效地进行傅-克烷基化反应. 此外, 催化剂能回收, 再次使用三次也没有明显地失去催化活性.

| Abstract: | Ce2(SO4)3 was used as an inexpensive and effective catalyst for the Friedel-Crafts alkylation of aromatic compounds with benzyl alcohols, allyl alcohols and benzyl chlorides. In the presence of 1～10 mol% of Ce2(SO4)3, Friedel-Crafts alkylation reactions of aromatic compounds with benzyl alcohols, allyl alcohols and benzyl chlorides were carried out smoothly and efficiently. Moreover, the catalyst could be recovered and reused three times without significant loss of activity. |
