| Abstract: The palladium and iridium substituted dodecamolybdophosphates with the general formula(Bu4N)n[PMo11M(OH2)O39] have been prepared and characterized by IR, UV and 31P NMR. The cyclic voltammetry measurement in acetonitrile solution revealed that the iridium substituted compounds displayed three reversible framework redox couples, however, no obvious redox peak was found for the palladium derivative, as a result of its strong adsorption on the surface of the electrod. Both substituted compounds served as bifunctional catalysts in the cyclohexene oxidation reaction by molecular oxygen. The main products were cyclohexen-2-ol and cyclohexene-2-one for the iridium substituted compounds, but cyclohexen-2-ol and phenyl ol instead for the palladium derivative. |
