Abstract

Abstract Friedel–Crafts acylation of alkoxy benzenes is achieved efficiently by reaction with aliphatic acid anhydrides in the presence of catalytic amounts of ferric hydrogensulfate, Fe (HSO4) 3, in nitromethane. Alkyl benzenes and aryl halides, as well as aromatic anhydrides, remain intact under these conditions.
