On Triazoles. XII. The Carbamoylation and Thiocarbamoylation of 5-Amino-1,2,4-triazoles

The reaction of 5-amino-3-R-1H-1,2,4-triazoles 1 with isocyanates 2 (X = O) and isothiocyanates 2 (X = S) was studied.Is was stated that with isocyanates 3a (X = O) type ring-carbamoylated products were formed which did not rearrange to the corresponding

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.
