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