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 benzylalcohols, including primary and secondary benzylalcohols, and allyl alcohol were carried out smoothly and efficiently. Moreover, the catalyst was recovered
In the presence of catalytic amounts of cationic thiolate-bridged
diruthenium complexes, arenes react with allylic alcohols to afford the
corresponding allylated aromatic products in high yields.

The highly active Friedel-Crafts alkylation (FCA) catalyst, [Ir(COD)Cl(SnCl3)(SnCl4)(arene)]+Cl- (1-SnCl4), is easily generated in one-pot from [Ir(COD)Cl]2 or [Ir(COD)(mu-Cl)Cl(SnCl3)]2 (1) and SnCl4. The reaction of arenes, heteroarenes with benzyl, and allyl alcohols is promoted by 1-SnCl4 (1 mol %) with high turnover frequency. Kinetic evidence is presented to establish FCA pattern.
