| Research Abstract |
In photocatalytic aerobic oxidation of cyclohexene catalyzed by 5,10,15,20-tetrakis (pentafluorophenyl) porphyriniron (III) chloride [Fe(TPFPP)Cl] under visible light irradiation, the coexistence of solid bases was found to enhance the selectivity to 1,2-epoxycyclohexane drastically. In the absence of solid bases, however, only the allylic oxidation of cyclohexene was catalyzed by the porphyrin complex acting as a sensitizer. Among the various metal oxides investigated, hydrotalcite exhibited the highest conversion of cyclohexene and selectivity to 1,2-epoxycyclohexane.
