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.

The photochemical reaction of a series of 2-aryl-1,2-benzisothiazol-3(2H)-ones (1) under deaerated conditions was found to give dibenzothiazepin-11(10H)-ones (2).A mechanism through a biradical species is proposed for the photoreaction.When the photolysis of 1 was carried out in the presence of oxygen, 2-aryl-1,2-benzisothiazol-3(2H)-one-1-oxides (11) were formed together with compounds 2.
