Catalytic activity of rare-earth-supported catalysts in Friedel–Crafts acylations

Abstract Friedel–Crafts acylations are catalysed by rare-earth-supported catalysts. The preparation, characterization and performance of these solid catalysts in a test acylation reaction and in a variety of syntheses of aromatic ketones are reported. In contrast to the reactions using AlCl 3 , the experimental conditions are non-polluting and the final work-up does not require any aqueous treatment.
