Oxovanadium Complex of 2-((2-aminophenyl) iminomethyl) 6-methoxy phenol, Preparation, Characteriziation and Catalytic activity in the oxidation of Benzoin

摘要

The oxovandium complex derived from Schiff base ligand namely [2-(2-aminophenyl) iminomethyl) 6-metzoxyphenol] result from condensation of 1, 2-phenylenedaimne and o-vanilin was synthesized and characterized by elemental analysis, IR, 1HNMR and EI-mass. The ligand acts as tridentate towards vanadylion via the azomethine nitrogen, phenolic oxygen and the lone pair of nitrogen atom of NH2. The thermogravemtric (TG) analysis confirm high stability of the complex. Their catalytic activity properties in H2O2 promoted oxidation of the benzoin to benzil was investigated.
