On triazoles. V. Synthesis of 1‐ and 2‐R1‐3‐R2,R3‐amino‐5‐amino‐1,2,4‐triazoles

Abstract
The correct isomeric and tautomeric structure of different 1‐ and 2‐R1‐3‐R2,R3‐amino‐5‐amino‐1,2,4‐triazole derivatives prepared from the correspondingN‐cyano‐N'‐R2,R3S‐methyl‐isothioureas and the corresponding hydrazines was proved with the help of their ir, uv,1H‐nmr and13C‐nmr spectra as well as the uv spectra of the Schiff bases of an isomeric pair.
