Abstract
Ytterbium(III) tris(perfluoroalkanesulfonyl)methides were found to be effec tive catalysts (10 mol%) for the Friedel-Crafts acylation of arenes with ac id anhydrides. In addition, with sufficient fluorous content in the ytterbi um complex, the reactions could be run under a fluorous biphase regime wher e the catalyst is recycled and re-used by extraction of the spent acylation reaction mixture with perfluoromethyldecalin.
