An new strategy that uses Ce2(SO4)3 as an effective catalyst for Friedel‐Crafts alkylation of aromatic compounds with benzyl and allyl alcohols is presented. In the presence of 1 to 10 mol% of Ce2(SO4)3, Friedel‐Crafts alkylation with both benzyl alcohols, including primary and secondary benzyl alcohols, and allyl alcohol were carried out smoothly and efficiently. Moreover, the catalyst was recovered
摘要 提出了一种使用 Ce2(SO4)3 作为芳香族化合物与苯甲醇和烯丙醇的 Friedel-Crafts 烷基化的有效催化剂的新策略。在 1 至 10 mol% 的 Ce2(SO4)3 存在下,苯甲醇(包括伯和仲苯甲醇)和烯丙醇的 Friedel-Crafts 烷基化反应顺利有效地进行。此外,催化剂被回收并重复使用3次,活性没有显着损失。
