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.

Reaction of N3-unsubstituted amidrazone ylides (1a and 1b) with alkyl or aryl isothiocyanates gives N3-thiocarbamoylamidrazone ylides (2).Thermolysis of 2 gives 3-alkyl(or aryl)-5-alkyl(or aryl)amino-1,2,4-thiadiazoles (a-i).
