the working electrode by insoluble electroactive poly(9,9‘-spirobifluorene-free and manganese porphyrin) films which
electrochemical behavior and physicochemical properties are described. After removal from the electrode, the
manganese-complexed polymers were evaluated as catalysts for the oxidation of alkenes by iodobenzene diacetate
or iodosylbenzene. The results show that the reactions proceeded very efficiently at room temperature with good
yields. The electrosynthesized polymer catalysts can be recycled by simple filtration and reused even up to the
eighth cycle without loss of activity and selectivity. These results represent an important improvement over those
previously described for manganese-porphyrin-catalyzed epoxidation reactions.
