Abstract

Abstract : A novel Fe3 O4 @P4VP@FeCl3 core–shell catalyst has been developed through coordination interaction between P4VP and FeCl3, which was utilized in selective oxidation of alcohols using molecular oxygen as the oxidant. Abstract : A novel magnetic Fe3 O4 @P4VP(poly(4-vinylpyridine))@FeCl3 core–shell structure was successfully synthesized. Its Fe3 O4 @P4VP core was initially prepared via polymerization of 4-vinyl pyridine on the surface of Fe3 O4 microspheres. The successful introduction of the FeCl3 moiety as a catalytic active site was achieved through coordination interaction between P4VP and FeCl3 . The obtained Fe3 O4 @P4VP@FeCl3 catalyst was applied in the selective oxidation of alcohols using molecular oxygen as the oxidant. It was shown that a variety of alcohol substrates is tolerated under optimized reaction conditions. Additionally, benzylic oxidation of hydrocarbon compounds was also evaluated using Fe3 O4 @P4VP@FeCl3 as the catalyst and t BuOOH as the oxidant, achieving high yields and very good selectivities. The heterogeneity of the Fe3 O4 @P4VP@FeCl3 core–shell catalyst was tested and the initial activity was maintained after five reuses.
