摘要：

A new dioxidomolybdenum(VI) complex, [MoO2(L)(CH3OH)] (1), was synthesized by the reaction of MoO3 with ONO-donor hydrazone ligand that is obtained from the condensation of benzolyacetone and furan-2-carbohydrazide in methanol. Both of the ligand and complex were characterized by elemental analysis and FT-IR, NMR and UV–Vis spectroscopic methods. The structure of complex was also determined by single crystal X-ray analysis. Structural analysis showed that the Mo(VI) ion has a distorted octahedral geometry and the ligand is coordinated to the metal ion as dinegative ONO-donor ligand. The obtained molybdenum(VI) complex was used as catalyst in oxidation of benzyl alcohol with H2O2 as a green oxidant. The effects of some parameters such as temperature, solvent and ratio of materials were also studied. Catalytic studies indicated that complex 1 can efficiently catalyze the oxidation of benzyl alcohol but its activity and selectivity are considerably dependent on the reaction condition. © 2020 Elsevier B.V.
