英文摘要	The oxidase and dioxygenase reactions of 3,5-di-tert-butylcatechol (DTBC, I) in the presence of V-polyoxometalate were studied. It was found that the addition of a Lewis base quenched the V-polyoxometalate-catalysed catechol dioxygenase reaction and catalysed the oxidase reaction selectively. The existence of V-polyoxometalate accelerates the autoxidation rate of I as demonstrated by the rate measurements. ESR and UV-VIS spectra showed that the Lewis base destroyed the dioxygenation reaction catalyst as formed and restrained its regeneration by suppressing the coordination of catechol radical to vanadium. The by-products of the dioxygenation and oxidation reactions are H(2)O and H(2)O(2), respectively.; The oxidase and dioxygenase reactions of 3,5-di-tert-butylcatechol (DTBC, I) in the presence of V-polyoxometalate were studied.
