The oxidation of organic compounds with carbon-carbon double bond with using of molecular oxygen under atmospheric pressure in the presence of new polyaniline supported catalyst 1 and 2 has been studied. These catalysts turned out to be efficient and selective for oxidation of unsaturated organic compounds as well as oxidation of hydrocarbon in benzyl position. Oxidation of alkenes and cycloalkenes gives corresponding epoxy derivatives, whereas oxidation of hydrocarbons in benzyl position gives ketones as the main products.
