The oxidation of organo-sulfides to sulfones has been accomplished using an easily accessible bifunctional ionic liquid, [pmim]IO4 in the absence of any other oxidants, metal and organic solvent at ambient temperature. A variety of sulfides including dialkyl, aryl–alkyl, diaryl, and aryl–hetero aryl have been oxidized to the corresponding functionalized sulfones in high yields by this procedure.
