Abstract: This paper first reported the catalysis for cyclohexane monooxygenation with PhIOat room temperature and in air atmosphere by μ-oxo-bisporphinatomanganese ( Ⅲ ) compounds.Compared with other metalloporphyrins reported so far, μ-oxo-bisporphinatomanganese ( Ⅲ) showed the better catalytic properties on cyclohexane hydroxylation.The kinetic researches found that there existed Hammett relationship between the substituents on porphyrin rings and the rate constants of the reactions catalyzed by μ-oxo-bisporphinatomanganese (Ⅲ).
