Abstract

The Friedel-Crafts acylation of anisole with acetic anhydride could be efficiently catalyzed by suitable silica-supported sulfonic acids. In particular, by using silica supported 4-ethylphenylsulfonic acid as catalyst it was possible to apply the synthetic procedure to different aliphatic anhydrides and aromatic compounds. It has been observed that the effect of the length of the alkyl chain of the anhydride is quite significant. Moreover, some attempts to regenerate the solid catalyst have been also discussed
