  Synthesis, Crystal Structures and Catalytic Property of Oxidovanadium(V) Complexes with Similar Aroylhydrazones

  摘要：

  A pair of new oxidovanadium(V) complexes, [(VOLL)-L-1]center dot EtOH (1) and [(VOLL)-L-2]center dot EtOH (2) (L = acetohydroxamate), derived from the aroylhydrazones N'-(5-bromo-2-hydroxybenzylidene)-4-methoxybenzohydrazide (H2L1 ) and N'-(5-bro-mo-2-hydroxybenzylidene)-4-methylbenzohydrazide (H2L2), have been prepared and characterized by elemental analyses, FT-IR, H-1 and C-13 NMR spectroscopy and single-crystal structural X-ray diffraction. The complexes have octahedral structures in which the aroylhydrazone ligands behave as binegative donors. Single-crystal structure analyses reveal that the V centers are coordinated by the donor atoms of the aroylhydrazone ligands, the acetohydroxamate ligands and the wddo groups. Crystal structures of the complexes are stabilized by hydrogen bonds. The complexes function as effective olefin epoxidation catalysts.
