摘要

A new procedure for the synthesis of 5(3)-nitroamino-l,2,4-triazole-3(5)-carboxylic acid and 5,5'-bi(3-nitroamino-l,2,4-triazole) potassium salt has been developed.It includes cyclization of [2-(N~2-nitro-carbamimidoyl)hydrazino]oxoacetic acid and 2,2'-bis(N~2-nitrocarbamimidoyl)oxalohydrazide,respectively,which are prepared by reaction of l-amino-2-nitroguanidine with oxalic acid.The reaction of 5(3)-nitroamino-l,2,4-triazole-3(5)-carbohydrazide with l-methyl-2-nitro-l-nitrosoguanidine leads to N'-(N~2-nitrocarbamimid-oyl)-5(3)-nitroamino-l,2,4-triazole-3(5)-carbohydrazide whose intramolecular cyclization in the presence of bases may be regarded as a new method of synthesis of 5,5'-bi(3-nitroamino-l,2,4-triazole) salts.
