The new role of 1,1-diamino-2,2-dinitroethylene (FOX-7): two unexpected reactions

Two novel derivatives of FOX-7, 2-methyl-5-nitro-1,2,3-triazole-4-amine (MNTzA) and 1,5-bis(1-amino-2,2-dinitrovinyl)carbonohydrazide (BADCh), were synthesized by two unexpected reactions of FOX-7 and hydrazino compounds, and the two reaction processes were analyzed. The reaction to form MNTzA is unusual among the syntheses of 2,4,5-trisubstituted 1,2,3-triazole compounds. The structures of the two compounds were studied by NMR, single crystal X-ray crystallography and theoretical calculations. MNTzA crystallizes in the monoclinic P2(1)/n space group with four molecules per unit cell, and each molecule exhibits good coplanarity. However BADCh shows serious structural distortion giving it a 'W' shape and possesses two highly polarized C-C double bonds. The DSC analyses and detonation properties of the two compounds were compared with those of FOX-7 and RDX, and the results indicate that MNTzA is an available intermediate for the synthesis of other complicated 2,4,5-trisubstituted 1,2,3-triazole compounds, and BADCh is an excellent energetic material and exhibits good thermal stability (thermal decomposition peak temperature >250 °C), with lower sensitivity (impact sensitivity >19.6 J and friction sensitivity 16%) and similar detonation properties (detonation pressure 32.1 GPa and detonation velocity 8.6 km s-1) when compared to FOX-7 and RDX.

C-H Amination of Nitro Azaheterocyclic Compounds by Vicarious Nucleophilic Substitution

Various nitro azaheterocyclic compounds were subjected to C H amination by vicarious nucleophilic substitution with 4H-1,2,4-triazol-4-amine (ATA). The aminated products were characterized by NMR, mass spectroscopy, and single-crystal X-ray diffraction an

Derivatives of 5-nitro-1,2,3-2H-triazole-high performance energetic materials

The energetic derivatives of 5-nitro-1,2,3-2H-triazole, which include 2-(methyl or amino)-4-(nitramino, azido, or nitro)-5-nitro-1,2,3-2H-triazoles, were prepared in moderate yields, and confirmed with NMR and IR spectroscopy, and elemental analysis. Their key properties, viz., melting and decomposition temperatures, densities, detonation pressures and velocities, and impact sensitivities, were measured or calculated. Among the new derivatives, 2-amino-4,5-dinitro-1,2,3-2H-triazole exhibits properties (Tm, 94 °C; Td, 190 °C; ρ, 1.83 g cm-3; P, 36.2 Gpa, vD, 8843 m s-1, IS, 24 J), comparable with RDX (T m, 205 °C; Td, 230 °C; ρ, 1.80 g cm -3; P, 35.0 Gpa, vD, 8762 m s-1, IS, 7.5 J), and may have potential as a high-performance energetic material.
