Using NMR spectroscopy, we have determined the relative stability and the effect of the solvent on the ratio of isomeric N,N-disubstituted 5-amino-1,2,3-thiadiazole-4-carbothioamides in a mixture.We carried out chromatographic separation of a mixture of 5

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.

The reaction of 5-mercapto-1,2,3-triazole-4-carboxamide with P4S10 was studied; the mechanism of this reaction is discussed. The effect of the donor-acceptor properties of the substituents on the direction of cyclization of the intermediate malonic acid α-diazodithioamide was investigated. A new rearrangement in the 5-mercapto-1,2,3-triazole series was observed.
