Abstract: The aim of present work was to check the possibility of microwave irradiation application for benzylic oxidation of diphenylmethane. The investigations were carried out using tert-butyl hydroperoxide (TBHP) both under conventional and microwave conditions. The catalysts tested were chlorides of transition d-metals: FeCl3·6H2O, CoCl2·6H2O, NiCl2·6H2O, CrCl3·6H2O, CuCl2·2H2O, ZnCl2 and iodine. From all studied metal catalysts, FeCl3·6H2O, CoCl2·6H2O, NiCl2·6H2O, CrCl3·6H2O showed the best catalytic activity.
Keywords: microwave irradiation, benzylic oxidation, tert-butyl hydroperoxide, d-metal chlorides
