  2-Nitroguanidine Derivatives: VI. Synthesis and Chemical Properties of Hydrazo- and Azobis(nitroformamidine)

  摘要：

  New methods have been proposed for the synthesis of hydrazobis(nitroforynamidine), and its reactions with electrophilic reagents, formaldehyde and glyoxal, have been studied. Oxidation of hydrazobis(nitroformamidine) with atmospheric oxygen in glacial acetic acid in the presence of a catalytic amount of N2O4 gives crystalline azobis(nitroformamidine). Ionization constants of the oxidation product, determined by potentiometric titration (pK(a)(1) = 3.50, pK(a)(2) = 7.93), indicate considerable increase in the NH acidity as compared to 2-nitroguanidine. Reactions of azobis(nitroformamidine) with P-dicarbonyl compounds lead to formation of 1-diacylmethyl-N'(1),N'(2)-dinitrohydrazine-1,2-dicarboximidamides.

  1,2-Dinitroguanidine is a product of nitroguanidine nitration with nitric acid and its mixtures with sulfuric acid and oleum. It is a diacid (pK(a), 1.11, similar to 11.5) and at the same time a weak base undergoing protonation at the nitrogen of the amino group (pK(BH) + -5.81). The decomposition kinetics of 1,2-dinitro-guanidine was studied by spectrophotometric method both in acid and alkaline media, and the mechanism of the process was assumed. In the media of high acidity (H-o > -8) the 1,2-dinitroguanidine suffers reversible denitration into nitroguanidine. At lower acidity its conjugate acid or molecular form undergoes hydrolysis yielding nitrourea. Monoanion of 1,2-dinitroguanidine in a weak acid or in an alkali is hydrolyzed into N,N'-dinitrourea. The reaction of 1,2-dinitroguanidine with alkali in alcohol provides its salts, with nitrogen-containing bases form both salts and derivatives of 2-nitroguanidine. The treatment of 1,2-dinitroguanidine with haloalkanes results in its N-alkylated products.

  Heterocyclization of hydrazine-1,2-bis(N-2-nitrocarboximidamide) and salts derived therefrom provides a procedure for the synthesis of 3,5-bis(nitroamino)-1,2,4-triazole salts. The presence of two acceptor nitroamino groups conjugated with the triazole ring considerably enhances the acidity of 3,5-bis(nitroamino)-1,2,4-triazole (pK(a)(1) = -2.0, pK(a)(2) = 4.8, pK(a)(3) = 10.6) as compared to mononitroaminotriazole, so that formation of salts with the corresponding dianion becomes possible.
