Synthesis and Properties of Tetranitro-Substituted Adamantane Derivatives.

Several new nitro-substituted adamantane compounds based on adamantane-1,3,5,7-tetrol were synthesized and the previously only briefly reported tetranitrate was reinvestigated. The materials were completely characterized by spectroscopic methods including some by X-ray diffraction. The energetic properties, thermal stabilities, and sensitivities of the nitrocarbamate, nitrocarbamate salt, and nitrate were determined and compared to current composites in terms of potential high-energy dense oxidizers (HEDOs). Furthermore, the enthalpies of all compounds were calculated, and their energetic performances investigated by using the EXPLO5 code.
