The reactions of dialkyl and alkyl aryl N-p-tosylsulfilimines with hydroxide or methoxide in methanol afforded either S-substitution products or Pummerer type products or a mixture of both, their distribution being dependent on the structure of the sulfilimine. From the results of analyses, the mechanisms of the formation of these products are discussed. A similar alkaline methanolysis of sulfonium
