The cyclization processes of 2-diazomalondithioamides, generated by five different methods, have been studied.The ambient character of the derivatives of 2-diazomalondithioamide is the cause of previously unknown rearrangements of 5-mercapto-1,2,3-triazole- and 5-amino-1,2,3-thiadiazole-4-N-R-carbothioamides to 5-N-R-amino-1,2,3-thiadiazole-4-carbothioamides.NMR 1H and 13C spectra and mass-spectra are presented for the series of 5-amino-1,2,3-thiadiazole derivatives.
