Manganese(III) porphyrin supported on polystyrene as a heterogeneous alkene epoxidation and alkane hydroxylation catalyst

Carboxymethylated crosslinked polystyrene resin [poly(4-styrylmethylacylchloride) (PSA)] support have been used to covalently attach manganese(III) tetrakis(4-aminophenyl)-porphyrin. This catalyst was found to be efficient for alkene epoxidation and alkane hydroxylation by sodium periodate. This new hydrogenised catalyst is of high stability and reusability.
