Descripción
H₄PMo₁₁VO₄₀, H₅PMo₁0V2O₄₀ and H₉PMo₆V₆O₄₀ acids and an acidic pyridinium salt of H₄PMo₁₁VO₄₀ were synthesized. They were characterized by FT-IR and the variations of their acid properties were determined by titration with n-butylamine. They proved to be highly active and selective catalysts for the hydrogen peroxide oxidation of methyl phenyl sulfide to the corresponding sulfoxide or sulfone. The conversion and selectivity results may be explained in terms of the co-existence of acidic and oxidative properties in the catalysts. On the other hand, a convenient catalytic homogeneous procedure has been found to oxidize different sulfides to sulfoxides or sulfones, with 35% aqueous H₂O₂, using (PyH)H₃PMo₁₁VO₄₀ as catalyst. The oxidation reaction is carried out at room temperature for sulfoxides or 40 °C for sulfones and requires a short time. The sulfoxides or sulfones were obtained with excellent yields by controlling the amount of H₂O₂.
