L,7-Diacetoxy-2,4,6-trinitro-2,4,6-triazaheptane

Substance (XXI) may subsequently undergo nitrolysis at K to form the nitramine ester l,7-diacetoxy-2,4,6-trinitro-2,4,6-triazaheptane (XXIII) (a chain compound BSX , m.p. 154-155°C) ... 

C1.CH2.N(N02) CH2.N(NC>2).CH 2-N(N02).CH2Cl mw 314.02, N 31-23% fine crysts (from benz), mp 144.5-45.5° bp - explodes was prepd by saturating with anhyd HCl at 10° a soln of l-acetoxy-7-trifluoroacetoxy-2,4,6i-trinitro-2,4,6-ftriazaheptane. GSX was also prepd from HCl Sic the diacetate of l,7-diacetoxy-2,4,6-trinitro-2,4,6-triazaheptane 1,7-bis-trifIuoro-acetoxy-2,4,6-trinitro-2,4,6Ttriazaheptane 8c HCl gave a 20% yield of GSX (Ref 3). Jones Thorn (Ref 2) deed its UV spectra, but did not report its prepn. The expl props of GSX were not detd... 

To protect the hydroxyl groups of the compound (VII) or (XIII) by acetylation Wright cooled a solution after nitrolysis to — 55°C and then added acetic anhydride at a temperature below — 25°C. Apart from cyclonite he isolated l-acetoxy-7-nitroxy-2,4,6-trinitro-2,4,6-triazaheptane (XIV). The addition of the solution from nitrolysis to acetic anhydride gave a diacetyl derivative 1,7-diacetoxy-2,4,6-trinitro-2,4,6-triazaheptane (XV) ...
