The title reaction occurs by an associative mechanism involving heterolytic O–O cleavage; the sequence azobenzene →(1)→(2)→ azophenol leading to overall regiospecificaromatic hydroxylation has been realised.

H(2)L(2) and p-Cl for H(2)L(3)], were prepared by the condensation of salicylaldehyde with 2-(o-hydroxy aryl)azo} aniline. Reaction of H(2)L with VOSO(4) afforded the oxovanadium complex, (L)V(O)(H(2)O). The (L(1))V(O)(H(2)O) complex displays two reversible responses at 0.7 V and -0.65 V vs. SCE in cyclic voltammetry. Catalytic activity of (L(1))V(O)(H(2)O) toward H(2)O(2) induced oxidation of organic thioethers
