在可见光照射下，5,10,15,20-四（五氟苯基）卟啉铁（III）氯[Fe(TPFPP)Cl]光催化氧化环己烯，发现固体碱的共存显著提高了对氧化环己烯的选择性。在没有固体碱的情况下，卟啉络合物作为增敏剂只催化环己烯的烯丙基氧化。在所研究的各种金属氧化物中，水滑石对环己烯的转化率和对环氧环己烯的选择性最高。
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 cyclohexene oxide 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 cyclohexene oxide.
