  • 2,5-Dipicrylfurans
    Patent number: 4061658
    Abstract: 2,5-Dipicrylfurans of the formula ##STR1## wherein R.sub.1 and R.sub.2 vary independently and are select from the gp consisting of H and NO.sub.2. Unsubstituted 2,5-dipicrylfuran (R.sub.1 = R.sub.2 = H) is prepared by reacting a picryl halide with a 2,5-dihalofuran. Unsubstituted 2,5-dipicrylfuran may be nitrated under selected conditions to produce either 2,5-dipicryl-3-nitrofuran (R.sub.1 = NO.sub.2, R.sub.2 = H) or 2,5-dipicryl-3,4-dinitrofuran (R.sub.1 = R.sub.2 = NO.sub.2). The 2,5-dipicrylfurans of this invention are energetic explosives possessing high thermal stability.
