摘要： COPPER POLYPHTHALOCYANINE WHICH HAS BEEN ACTIVATED BY CONTACT WITH AN AROMATIC HETEROCYCLIC AMINE TO FORM A NOVEL COMPLEX IS FOUND TO BE AN EFFECTIVE CATALYST FOR THE OXIDATION OF SECONDARY AND TERTIARY ALKYL AROMATICS SUCH AS ETHYLBENZENE OR CUMENE TO FORM THE CORRESPONDING HYDROPEROXIDE. THE RATE OF CONVERSION AND THE PERCENTAGE YIELD IS GREATER THAN THAT WITH COPPER PHTHALOCYANINE OR COPPER POLYPHTHALOCYANINE PER SE.
