The reactions of N-alkyl- and N-aryl-2-(methylsulfinyl)benzamides and N-[2-(methylthio)benzoyl]-N-alkylhydroxylamines with thionyl chloride have been found to give 2-substituted 1,2-benzisothiazol-3(2H)-ones in nearly quantitative yields. The reactions of N-[2-(methylthio)benzoyl]-N-arylhydroxylamines with thionyl chloride gave chlorinated anilides as the major products.
