Friedel-Crafts acylation is carried out with several aromatic substrates in the presence of an electrochemically active aluminium anode to minimize the inorganic reagents. Only a catalytic amount of AlCl 3 (5 mol %) is required to enable the anodic polarization of the aluminium electrode to promote

The stable and non-hygroscopic aluminum dodecatungstophosphate (AlPW 12 O 40 ), was found to be an effective catalyst (3 mol%) for the solvent-free Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the presence of trifluoroacetic anhydride under mild reaction conditions.
