Synthesis and characterization of a new cage-like energetic compound 3,7-dinitrato-9-nitro-9-azanoradamantane

Abstract

Organic cage-like frameworks are important and versatile skeletons for developing prospective energetic compounds because of their high intrinsic density, symmetry, stability, and derivability. In this paper, a noradamantane-based energetic compound 3,7-dinitrato-9-nitro-9-azanoradamantane was synthesized from easily accessible compound 1,6-heptadien-4-ol via eight steps. Based on the X-ray diffraction analysis, it exhibits a good density of 1.678 g⋅cm⁻³. Thermogravimetry (TG) and differential scanning calorimetry (DSC) tests indicate that it has positive thermal stability since its decomposition temperature was found to be 134 °C, and the theoretical detonation velocity is calculated to be 7363 m⋅s⁻¹. These results imply that noradamantane has the potential to be a prospective framework for developing high energy-density energetic compounds.
