  Synthesis of 5-Substituted N-Nitro-2,4-dihydro-3H-1,2,4-triazol-3-imines

  摘要：

  The reaction of N-amino-N ''-nitroguanidine with carboxylic acid chlorides at room temperature gave the corresponding N-(N ''-nitroguanidino)carboxamides which underwent cyclization on heating in aqueous alkali to affordN-nitro-1,2,4-triazol-3-imines. The latter were also synthesized in a one-pot fashion. The products were characterized by H-1 and C-13-{H-1}, IR, and UV spectra.

  The interaction of 1-methyl-1-nitroso-2-nitroguanidine with carboxylic acid hydrazides results in formation of N-(2-nitroguanidino)amides that easily give 3(5)-nitroamino-5(3)-alkyl(aryl)-1,2,4-triazoles under refluxing in aqueous alkaline medium. We have developed a one-pot method to prepare such heterocyclic structures; the synthesis of one of the sample compound has given an example of the method applicability. The compounds structures have been confirmed by UV, IR, H-1, and C-13-H-1} NMR spectroscopy.
