Aryl-, and vinyltrichloromethanes 1 are transformed with antimony pentachloride to α,α-dichlorocarbenium salts 2, which react with sulfinylamines 3 to afford nitrilium salts 4 in good yields. In contrast to this preparatively useful reaction, the reaction of α-monochlorocarbenium ions 8 (obtained from diaryldichloromethanes 7) with sulfinylamines 3 affords mixtures of iminium salts 10, isoindolium salts 13, and 2-azoniaallene salts 14.
芳基三氯甲烷和乙烯基三氯甲烷 1 用五氯化锑转化为 α,α-二氯碳鎓盐 2,其与亚磺酰胺 3 反应,以良好的产率提供硝基鎓盐 4。与此制备有用的反应相反,α-一氯碳鎓离子 8(从二芳基二氯甲烷 7 获得)与亚磺胺 3 的反应提供亚胺盐 10、异吲哚盐 13 和 2-azoniaallen 盐 14 的混合物。
