The oxidation of 8-methoxypsoralen (2) with hydrogen peroxide and potassium superoxide catalyzed by 5, 10, 15, 20-(2, 4, 6-trimethylphenyl)porphyrinatoiron(III) chlorides [Me_12-TPPFe(III)Cl] (la) and 5, 10, 15, 20-(2, 6-dichlorophenyl)porphyrinatoiron(III) chlorides [Cl_8TPPFe(III)Cl](1b) in dichloromethane gives 6-formyl-7-hydroxy-8-methoxycoumarin (3) in moderate yields, whereas the oxidation of (2) with H_2O_2 catalyzed by 5, 10, 15, 20-(2, 6-dichlorophenyl)-β-octahaloporphyrinatoiron(III) chlorides [Cl_8βX_8TPPFe(III)Cl](X=C1, Br)(1c, 1d) gives specifically 5, 8-dioxopsoralen (4) in moderate yields.
