| Abstract: | In order to mimicking the active center of the VHPO, we designed and synthesized a series of oxovanadium complexes containing poly(pyrazolyl)borate ligands: VO(HB(3,5-Me2pz)3)(3,5-Me2pz)(HOOCCH2CH2COO) and VO(HB(3,5-Me2pz)3)(3,5-Me2pz)(C5H4N-COO), and they have been characterized by X-ray single crystal diffraction. Based on vanadium(V) complexes catalyzing the visible conversion of phenol red to bromophenol blue under weak-acid conditions, we investigated the role of the oxovanadium complexes in the bromide oxidation reaction. It is found that the oxovanadium (IV) complexes can be considered as potential functional model of vanadium-dependent haloperoxidases. And the mechanism of the catalytic reaction is analyzed by molecular orbital theory. |
