A variety of N-substituted l,2-benzisothiazolin-3-ones were easily synthesized from N,N'-disubstituted 2,2'-dithiodibenzamides in the presence of O-methylhydroxylamine hydrochloride. Derivatives with a primary, secondary,or tertiary alkyl group or an aryl group on the N-1 nitrogen of the l,2-benzisothiazolin-3-one were obtained.
在O-甲基羟胺盐酸盐存在下,N,N'-二取代的2,2'-二硫代二苯甲酰胺很容易合成出多种N-取代的L,2-苯并异噻唑啉-3-酮。获得了在1,2-苯并异噻唑啉-3-酮的N-1氮上具有伯、仲或叔烷基或芳基的衍生物。
