title: [Manganeseporphyrin/vanadium-substituted polyoxometalate new coordination compound: synthesis, characterization and catalytic activity].
abstract: A new kind of manganeseporphyrin/vanadium-substituted polyoxometalate coordination compound was synthesized by meso-tetrakis(4-trimethylamidiophenyl) manganeseporphyrin and vanadium-substituted polyoxometalate H5 PMo10 V2O4 reacting in water solution at room temperature, and its structures were studied by IR spectrometry and UV-Vis spectrometry. The results show that metalloporphyrin ring structure and polyoxometalate cage structure still exist in the coordination compound, and these two parts connect with each other by chemical bond. As an excellent catalyst, its effects on benzene hydroxylation and catalytic capabilities were studied with H2O2 solution as an oxidant under mild reaction condition, meanwhile the catalytic active centre in the benzene hydroxylation reaction was discussed. The results indicated that V atom in polyoxometalate is the main centre of catalytic activity, while the presence of manganeseporphyrin could improve its catalytic activity greatly.
