The compounds of the formula ##SPC1## In which R independently is hydrogen, lower alkyl, lower alkoxy, halo or trifluoromethyl; x is 1 to 2; n is 1 to 3, and R.sub.1 and R.sub.2 independently are hydrogen, lower alkyl or phenyl and together with the nitrogen atom form a heterocycle which may contain an oxygen atom as a hetero atom. The compounds are prepared by reacting the corresponding N-substituted-1-(arylthio)methanesulfonamide with small, incremental amounts up to substantially equimolar of 30% hydrogen peroxide in glacial acetic acid at 65.degree.-70.degree. C., to obtain the sulfinyl compound, or substantially two equimolar proportions of 30% hydrogen peroxide in glacial acetic acid at reflux temperature to obtain the sulfonyl compound, and recovering the corresponding sulfinyl or sulfonyl product.
式为##SPC1##的化合物,其中R独立地为氢、低烷基、低烷氧基、卤素或三氟甲基;x为1到2;n为1到3,且R.sub.1和R.sub.2独立地为氢、低烷基或苯基,并与氮原子一起形成一个杂环,该杂环可能包含一个氧原子作为杂原子。通过将相应的N-取代-1-(芳基硫基)甲磺酰胺与小的、逐步增加的30%过氧化氢在冰乙酸中于65℃-70℃反应,以获得亚磺酰化合物,或在沸腾温度下用基本上两个当量的30%过氧化氢在冰乙酸中反应,以获得磺酰化合物,并回收相应的亚磺酰或磺酰产物。
