Herein, we report an electrochemical method for the synthesis of benzisothiazol-3(2H)-ones from 2-mercaptobenzamides. The electrochemical reaction proceeds through intramolecular N[sbnd]H/S[sbnd]H coupling cyclization reaction by generating H2 as the nonhazardous side product. Moreover, the developed procedure is highly advantageous due to its short reaction time, mild conditions and wide substrate scope without the employment of metal catalyst and exogenous-oxidant.2009 Elsevier Ltd.

An efficient and versatile Co-catalyzed intramolecular S-N bond formation in water to synthesize 1,2-benzisothiazol-3(2H)-one and 1,2,4-thiadiazoles derivatives in good to excellent yields was developed. The transformation showed great tolerance with a broad range of substituents. The mother liquor was able to be recycled 6 times with minor loss in product yield.
