Reaction Steps
A solution of 5-fluoro-1,3-diamino-2,4,6-trinitrobenzene (F-DATB) (5.22 g, 20 mmol) and cyanotrimethylsilane (4.96 g, 50 mmol) in CH3NO2 (100 ml) was refluxed for two hours and then evaporated under vacuum to leave a solid residue. Recrystallization from acetonitrile (100 ml) gave 5-cyano-1,3-diamino-2,4,6-trinitrobenzene (4.4 g, 82%) as orange-brown crystals: mp 212°-217° C. dec. An additional recrystallization gave the analytical sample: mp 220°-221° C.; mass spectrum (CI, CH4) m/z 269 (M+1, 100).
