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. The Royal Society of Chemistry 2009.

6H-Dibenzopyran-6-carboxylic acid described in a preceding communication was an intermediate to compounds provided of immunomodulating and hypolipidemic activity.The synthesis of the thio analogue 8 is now reported.The key intermediate, 6H-dibenzothiopyran-6-ol, 6, was obtained via Pschorr cyclization and Pummerer rearrangement.In comparison with the corresponding 6H-dibenzopyran-6-ol, compound 6 was less reactive toward some nucleophiles.
