STUDIES ON THE SYNTHESES OF METALLOPORPHY RINS AND BIOMIMESIS FOR CYTOCHROME P-450(XIV) .14. CATALYSIS OF TPPCO(II) FOR CYCLOHEXANE MONOOXYGENATION

This paper reports the catalysis of TPPCo(I) for cyclohexane monooxyge nation with PhIO, The kinetic properties, the temperature effect and t he effect of axial ligands of the reactions were studied. The results show that TPPCo(I) with axial ligand pyridine can catalyze cyclohexane monooxygenation with PhIO and that the catalytic properties are relat ed to the reaction temperature and the quantity of pyridine. The rates of the reactions can increase with the increase of the reaction tempe rature. There is Arrhenius relationship between the rate constants of the reactions and the reaction temperature, The yields of the products decrease with the increase of the reaction temperature. The catalytic effect of TPPCo(I) is the best when the quantity of pyridine is 50 ti mes that of TPPCo(I).
