H2SO4 mixed with silica gel (1:2) by weight produces a white powder which is an effective catalyst for the oxidation of thioethers to their corresponding sulfoxide by MnO2 under solvent-free conditions.

(Chemical Equation Presented) Various types of aromatic and aliphatic sulfides are selectively oxidized to sulfoxides and sulfones in good to excellent yields using 30% H2O2 in the presence of catalytic amounts of a novel recoverable silica-based tungstate interphase catalyst at room temperature. The catalyst can be recovered and reused for at least eight reaction cycles under the described reaction conditions without considerable loss of reactivity.
