The effects of both the constructions of metalloporphyrins and environment factors such as reaction solvents, reaction temperature and reaction time on the percentages of cyclohexanone in cyclohexane hydroxylation with PhIO catalyzed by monometalloporphyrins or bismetalloporphyrins and the reaction kinetics were studied systematically. The cyclohexanol oxidation with PhIO catalyzed by the metalloporphyrins was compard with the cyclohexane oxidation. The mechanism of the ketone formation in the alkane hydroxylation with PhIO catalyzed by metalloporphyrins was supposed.
