Oxidation of S,S-Diaryl-N-(p-tolylsulfonyl)sulfilimines and N-Unsubstituted S,S-Diaryl-sulfilimines with Potassium Hyperoxide Anion Radical (O2-.) in the Presence of 1-Bromopropane, Benzoyl Chloride, p-Tolylsulfonyl Chloride, Carbon Tetrachloride, Chloroform, or Dichloromethane in

The reaction of S,S-diaryl-N-(p-tolylsulfonyl)sulfilimines and N-unsubstituted diaryl-sulfilimines with hydroperoxide anion radical (O2^-.) in the presence of 18-crown-6 as a catalyst together with 1-bromopropane/benzene, benzoyl chloride/benzene, p-tolylsulfonyl chloride/benzene, carbon tetrachloride, chloroform, or dichloromethane, gave the corresponding sulfoximines, through nucleophilic oxidation with an intermadiary dioxy species formed upon treatment of organic halides with potassium hyperoxide (KO2).
