Recent developments on energetic di- and trisubstituted cubanes

Abstract. Although the cubane cage system was synthesized 60 years ago, some features are still unexplored. Apart from some carboxylates, no salts containing an anionic cubane moiety are reported. With the recent synthesis of cubane-1,4-dimethylnitrocarbamate (CMNC), several salts containing this energetic anion have now been synthesized and characterized. In addition, several tri-substituted energetic cubane derivatives were prepared. The compounds were characterized in detail, such as using heteronuclear NMR spectroscopy. Furthermore, the compounds were examined by DSC and sensitivity measurements for impact and friction.
