The reaction of N-cyanocarbonimidodithioic acid di(alkyl and aralkyl)esters with different alkyl-, aralkyl- and aryl hydrazines to yield 1-substituted-3-R-thio-5-amino-1H-1,2,4-triazoles (3) and 2-substituted-3-R-thio-5-amino-2H-1,2,4-triazoles (4) was studied.Isolation of the different types of isomeric pairs of 3 and 4 helped to prove the structure of products obtained which made possible correction of some confusion in the literature.The 3 (R = H) tautomeric structure of the non-substituted derivatives was supported by comparison of their uv and cmr spectra with those of the alkylated and aralkylated derivatives 3 and 4, respectively, again correcting confusion in literature.An hplc determination of the ratio of products 3 and 4 formed in the above reactions with different hydrazines made it possible to prove the mechanism of the reaction.
