英文摘要Four new oxovanadium(V) complexes, [VO(aha)L-1] (1), [VO(aha)L-2] (2), [VO(aha)L-3] (3), and [VO(aha)L-4]. EtOH (4) (Haha = acetohydroxamic acid, H2L1 = 4-nitrophenyl 2-(2-hydroxybenzylidene)hydrazinecarboxylate, H2L2=N'-(2-hydroxylbenzylidene)-4-methoxybenzohydrazide, H2L3 =N'-(2-hydroxylbenzylidene)-4-methylbenzohydrazide, HL4 = N'-(5-bromo-2-hydroxybenzylidene)-3-methyl benzohydrazide), have been prepared and structurally characterized by physico-chemical methods and X-ray diffraction. The V atoms in the complexes are in octahedral coordination, with the three donor atoms of the hydra zone ligand and the deprotonated hydroxyl O atom of the aha ligand defining the equatorial plane, and with the carbonyl O atom of the aha ligand and one oxo O atom occupying the axial positions. Crystal structures of the complexes are stabilized by hydrogen bonds. In addition, the catalytic performances for the peroxidative oxidation (with hydrogen peroxide) of complexes 1-4 and their starting materials VO(acac)(2) were studied by the reaction of styrene (St) to benzaldehyde (BzA) (the maximum total turnover number is 667) under the mild conditions.
