Cubane-based nitramines

The incorporation of the nitramino group into the core of cubane has not yet been achieved. However, a number of cubane-based energetic nitramines and nitramides have been synthesized.

The energetic cubane-based nitramine (22) is also synthesized from the direct A-nitration of the parent amine using a mixture of trifluoroacetic anhydride and nitric acid. ... 

Eaton and co-workers ° synthesized the cubane-based dinitrourea (42) via iV-nitration of the cyclic urea (41) with nitric acid-acetic anhydride. Cubane-based nitramide (43) is prepared from the IV-nitration of the corresponding bis-amide with acetic anhydride-nitric acid. Bis-nitramine (44) is prepared from the IV-nitration of the corresponding diamine with TFAA-nitric acid. ...
