S‐[ N '‐ (Chlorocarbonyl)amino]isothiocarbamoyl chlorides (II), obtained from S‐chloroisothiocarbamoyl chlorides (I) and isocyanates, react with primary aliphatic and aromatic amines to form the unknown class of 5‐imino‐1,2,4‐thiadiazolidin‐3‐ones. The structures were confirmed by chemical means and by spectroscopic methods.
