Synthese von substituierten 5-Amino-1,2,4-triazolen

Synthesis of Substituted 5-Amino-1,2,4-triazoles N-Nitro-amidino-dithiocarbimidic acid dimethylester 1 reacts with monosubstituted hydrazines under formation of the substituted 5-amino-1, 2, 4-triazoles. Disubstituted hydrazines give under the same conditions N-nitro-amidino-S-methyl-isothiosemicarbazides. The reaction of some more hydrazine derivatives with 1 yields the adequate substituted 1, 2, 4-triazoles.
