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.

Key words: allyl alcohol, Friedel-Crafts alkylation, aromatic compound, benzyl chloride, benzyl alcohol, Ce2(SO4)3
