Popis: 3-Nitro-1,2,4-triazol-5-one and its monomethyl derivatives react with methyl vinyl ketone to give products of addition to the ring N1 and N4 atoms. The reaction with formaldehyde and N-methylolacetamide proceeds only at the N1 atom. The keto derivatives of 3-nitro-1,2,4-triazol-5-one undergo the Schmidt reaction to give the corresponding acetamides. A number of compounds that include functional groups in the N1-alkyl substituent of the 3-nitro ring were obtained by treatment of the bases of N1-substituted 3,5-dinitro-1,2,4-triazoles in aprotic media.
