Energetic 1,2,5‐Oxadiazolo‐Pyridazine and its N‐Oxide
Abstract
Achieving an energetic compound, which exhibits high performance and insensitivity, is important in the field of energetic materials and remains a major challenge. Herein, we found that oxidation of 4,7‐diaminopyridazino[4,5‐c]furoxan (5) with a mixture of 50 % hydrogen peroxide and trifluoroacetic anhydride gave 6‐amino‐7‐nitro‐[1,2,5]oxadiazolo[3,4‐c]pyridazine (7) and its N‐oxide derivative (8). The oxidation of 5 with hypofluorous acid (HOF) was also studied. Compound 8 displayed an energetic performance compared to triaminotrinitrobenzene (TATB) and insensitive properties (impact sensitivity (IS) 36 J and friction sensitivity (FS)>360 N). Such excellent properties make 8 attractive for high‐performance applications, in which insensitivity is important.
