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 keto
nes are reported. In contrast to the reactions using AlCl3, the experimenta
l conditions are non-polluting and the final work-up does not require any a
queous treatment. (C) 1999 Elsevier Science B.V. All rights reserved.
