The oxovanadium(IV)-salophen catalysedoxidative decarboxylation of phenylsulfinylacetic acids by H2O2has been studied spectrophotometricallyin 100% acetonitrile medium under the influence of nitrogen bases like pyridine (Py), imidazole (ImH) and 1-methylimidazole (MeIm).Kineticresults reveal that the reaction rate is highly sensitiveto the nature of baseand strongly retarded by the nitrogen bases.The hydroperoxo species formation and an electrophilic attack of sulfur atom of PSAA on the nucleophilic peroxo oxygen of the vanadium complex is proposed as the mechanistic pathway of the reaction. The linear Yukawa-Tsuno plot correlates that the ground state stabilization of PSAAs through resonance interaction is the cause for the observed non linearity in the Hammett plot.
