Synthesis and catalytic activities in cyclohexane hydroxylation of metalloporphyrins supported on styrene-methylacrylic acid copolymer microspheres

Through a new synthetic strategy, metalloporphyrins (M = Fe(III), Mn(III) or Co(II)) were covalently immobilized on styrene-methyl acrylic acid copolymer microspheres. These copolymer-immobilized metalloporphyrins were found to be more efficient catalysts than the analogous non-supported metalloporphyrins for cyclohexane hydroxylation in metalloporphyrin-O-2-ascrobate mixtures. The catalytic activities of the immobilized catalysts follow the order Fe>Mn>Co.
