The catalytic performance of calix[6] arene-bismetalloporphyrins in oxidation of isopropyl benzene has been studied. The results show that calix[6] arene-bismetalloporphyrins possess much higher catalytic activity than the corresponding metalloporphyrin while displaying the sam eselectivity by giving rise to acetophenone as the ketonic component in excellent yield. This result is different from the usual reactions catalyzed by metallophthalocyanine and other macromolecule such as Schiff base metal chelate, where the ketonic component is acetone. The effects of temperature, axial ligands, amounts of catalyst used, and the variety of central metal etc. on the oxidation are also studied.
