【Abstract】 The heteropolyoxometalates mono substituted by transition metal, such as [( n C 4H 9) 4N] 8 n ·[PZ n+ BrMo 11 O 39 ] (Z=Mn 2+ , Fe 3+ , Co 2+ , Ni 2+ , Cu 2+ ), show good catalytic activity for the oxidation of cyclohexene using H 2O 2 as oxidant. On the basis of the results of kinetics, IR spectra and electrochemistry studies, the reaction mechanism was discussed. It is suggested that the substituted heteropolyoxometalate reacts with H 2O 2 to form an intermediate, and the substituted transition metal ion seems to be the center of activating H 2O 2.更多还原
