3-Substituted oxetanes are valuable monomers for modern ring-opening polymerizations. A new solid-state oxidizer, 3,3-dinitratooxetane (C3H4N2O7), which has an oxygen content of 62.2% was synthesized by the addition of N2O5 to oxetan-3-one. Monoclinic single crystals suitable for X-ray diffraction (ρ 1.80 g cm-3) were obtained by recrystallization from dichloromethane. In addition, 3-nitratooxetane was prepared by an improved method and 3-nitrato-3-methyloxetane was synthesized for the first time. Theoretical calculations were computed by the EXPLO5 software and additionally sensitivities towards impact and friction were determined.
