摘要：

Trifluoroacetic anhydride was used as an efficient activator of the acylation of aryl methyl ketones with carboxylic acids in the presence of Bronsted and Lewis acids (SF3SO3H, MeSO3H, 4-MeC6H4SO3H center dot H2O, BF3 center dot Et2O). In all cases, the products were the corresponding beta-diketones. In the reactions in the presence of boron trifluoride-diethyl ether complex, the products were isolated as BF2-chelates with high yields.
