摘要

The free ligands, 2-{(o-hydroxyaryl)azo}-1-N-salicylidene phenylamine, H2L [where H2L = RC6H4NNC 6H4NCH-C6H4OHR = p-H for H 2L1, p-Me for H2L2 and p-Cl for H2L3], were prepared by the condensation of salicylaldehyde with 2-{(o-hydroxy aryl)azo} aniline. Reaction of H2L with VOSO4 afforded the oxovanadium complex, (L)V(O)(H 2O). The (L1)V(O)(H2O) complex displays two reversible responses at 0.7 V and -0.65 V vs. SCE in cyclic voltammetry. Catalytic activity of (L1)V(O)(H2O) toward H 2O2 induced oxidation of organic thioethers to sulfoxide and sulfones have been examined. The cytotoxicity of (L1)V(O)(H 2O) has also been examined on human lung cancer cells.
