Synthesis, X-Ray Crystal Structure of Oxidovanadium(V) Complex Derived from 4-Bromo-N’-(2-hydroxybenzylidene)benzohydrazide with Catalytic Epoxidation Property

摘要

A new oxidovanadium(V) complex, [VOL(OCH 3 )(CH 3 OH)], where H 2 L = 4-bromo- N’ -(2-hydroxybenzylidene)benzohydrazide, has been synthesized and fully characterized on the basis of CHN elemental analysis, FT-IR, UV-Vis, 1 H and 13 C NMR spectroscopy. Structures of the free hydrazone and the complex were further characterized by single crystal X-ray diffraction, which indicates that the V atom in the complex adopts octahedral coordination, and the hydrazone ligand behaves as a tridentate ligand. The catalytic epoxidation property of the complex was investigated.
