摘要

Aerobic oxidation of benzene was carried out over the organic-inorganic hybrid catalyst of [(C₃CNpy)₂Pd(OAc)₂]₂HPMoV₂, a solid catalyst containing the Keggin polyoxometalate PMoV₂ and noble metal Pd(OAc)₂ in its ionic structure. The features of this heterogeneous reaction system were studied by tuning various reaction parameters including solvent selection, function of buffer agent, and effects of reaction time, reaction temperature and catalyst amount. The results show the high phenol yield of 9.8% without aided by any sacrificial reducing reagents. The conjugation of Pd(OAc)₂ and PMoV₂ within the ionic structure of [(C₃CNpy)₂Pd(OAc)₂]₂HPMoV₂ that accounts for its high activity is preliminarily discussed.
