Abstract

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.
