Benzoylations of several benzene, naphthalene and thiophene derivatives with benzoyl chloride or benzoie anhydride, catalyzed with EPZG catalyst and in the absence of solvents were studied under microwave irradiation (MWI). Reasonable to good yields of products were achieved in short times.

The regiochemistry of the reaction of 2-methoxynaphthalene 1 with benzoyl chloride 2a using a catalytic amount of Lewis acid is strongly influenced by the identity of the acid catalyst employed as well as by the reaction temperature.By using InCl3, FeCl3, SnCl4 or ZnCl2 and heating at 160 deg C, 2-benzoyl-6-methoxynaphthalene 4a is selectively produced along with 1-benzoyl-7-methoxynaphthalene 5a, while in the case of AlCl3, SbCl5 or TiCl4, 1-benzoyl-2-methoxynaphthalene 3a is the major product. 2-Acyl-6-methoxynaphthalenes 4b-e can be selectively obtained using InCl3 and the corresponding acyl chlorides 2b-e in place of 2a.In the presence of a stoichiometric amount of InCl3, the reaction of 1 with 2a also gives 4a as the predominant product along with 5a even at 50 deg C.This reaction appears to involve isomerisation of 3a to 4a and 5a.
