| Summary: | Adamantane is an important and versatile skeleton for synthesis of a large number of cage-like energetic compounds since its high intrinsic density, symmetry, stability, and derivability. Herein, a novel cage-like energetic compound, 4,4,8,8-tetranitro-2-oxaadamantane was synthesized in an overall yield of 21.1% from easily accessible compounds through six steps. Thermogravimetry (TG) and differential scanning calorimetry (DSC) tests indicate that it has excellent thermal stability since its decomposition temperature was found to be 288 °C, and the theoretical detonation velocity is calculated to be 6955 m/s. These results imply that the as-prepared compound has the potential to be applied as heat-resistant explosive.
