The condensation of dinitromethane with glyoxal has been investigated and it has been demonstrated that 1,1,4,4-tetranitro-2,3-butandiol, alpha-hydroxy-beta,beta-dinitropropionic acid or their mixture may be formed. Interaction of 1,1,4,4-tetranitro-2,3-butandiol or 1,4-dibromo-1,1,4,4-tetranitro-2,3-butanediol diacetates with sodium azide leads to bis(5-nitro-1,2,3-triazol-4-yl) via intermediate 1, 1,4,4-tetranitro-1,3-butadiene.

1,1,4,4-Tetranitrobutane-2,3-diol reacts with formaldehyde, forming 2,2-dinitropropane-1,3-diol or a cyclic ether - 4,4-dinitro-2,3-dihydroxytetrahydrofuran - as a function of the reaction conditions.

The synthesis of 1,1,4,4-tetranitrobutane-2,3-diol has been carried out via the reaction of the dinitromethane potassium salt with glyoxal, at pH values of 7-8 after reagent mixing and 5.5 at the end of the reaction, in the temperature range 35-37-degrees-C. X-ray crystal structure analysis has been performed on 1,1,4,4-tetranitrobutane-2,3-diol and its diacetate. The conformations of these molecules are stabilized to a significant extent by O-...N+-type electrostatic interaction, which was confirmed by quantum-mechanical calculations on 2,2-dinitroethanol as a model molecule.

A two-step has been proposed to obtain 1,12-difluoro-1,1,3,5,5,8,8,10,12,12-decanitro-3,10-diazadodecane-6,7-diol dinitrate, starting from 1,1,4,4-tetranitrobutane-2,3-diol and N-(methoxymethyl)-2-fluoro-2,2-dinitroethylamine, followed by nitration of the Mannich base formed. An x-ray-diffraction investigation of the dinitrate obtained was carried out.
