STUDY ON THE MECHANISM OF CYCLOHEXANONE F ORMATION IN CYCLOHEXANE HYDROXYLATION CATALYZED BY METALLOPORPHYRINS

The effects of both the constructions of metalloporphyrins and environ ment factors such as reaction solvents, reaction temperature and react ion time on the percentages of cyclohexanone in cyclohexane hydroxylat ion with PhIO catalyzed by monometalloporphyrins or bismetalloporphyri ns and the reaction kinetics were studied systematically. The cyclohex anol oxidation with PhIO catalyzed by the metalloporphyrins was compar ed with the cyclohexane oxidation. The mechanism of the ketone formati on in the alkane hydroxylation with PhIO catalyzed by metalloporphyrin s was supposed.
