Efficient aerobic oxidation of cyclohexene to the corresponding products catalyzed by iron (III) porphyrins in supercritical carbon dioxide (scCO 2 ) has been developed. Compared with the oxidation occurred in dichloroethane, the efficiency was improved significantly in scCO 2 , in which the cyclohexene conversion increased from 10.5% to 22.4%. Influence of various reaction parameters including catalyst, catalyst dosage, reaction temperature and pressure on the activity and selectivity were investigated in detail. Moreover, a plausible mechanism involving free radical and high-valence iron species was proposed.
