A ring-opening process of 4-imino-l,3-thiazetidin-2-ones with NH_2OH·HC1 was described for the first time.Two different scaffolds of imidodicarbonic diamide were obtained selectively in good yields in the presence of organic base.The obtained imidodicarbonic diamides were demonstrated by X-ray diffraction analysis.
