|Title:||Synthesis, characterization, and reactivity of vanadium(V) complexes containing coordinated peroxide and histidine-A model for the active site of enzyme bromoperoxidase|
|Abstract:||Vanadium(V) complexes of the type A[VO(O2)2(Hist)] (A=H+ or NH; Hist=histidine) and [DmpzH][VO(O2)2(Dmpz)](Dmpz=3,5-dimethylpyrazole) have been synthesized from the reactions of V2O5 or NH4 VO3 with H2O2 in the presence of histidine or 3,5-dimethylpyrazole. The complexes have been characterised by elemental analyses, IR, 1H, 13C and 51V NMR and electronic spectroscopic studies. Histidine has been shown to coordinate to vanadium centre through its imidazole nitrogen. Bromination of acetanilide by H[VO(O2)(Hist)] and oxidising capability of [DmpzH][VO(O2)2(Dmpz)] are also reported.|
