Abstract
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°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.
