Abstract
AbstractN5‐(2‐fluoro‐2,2‐dinitroethyl)‐N1‐methyl‐1H‐tetrazole‐5‐amine and its nitramide were designed and synthesized by a strategy based on functionalized amino group in 5‐amino‐1H‐tetrazole. Their structures were fully determined by 1H, 13C NMR, infrared spectrum as well as elementary analysis. Single‐crystal X‐ray diffraction was employed for characterizing their crystal structures. Comparing with its nitramide N5‐(2‐fluoro‐2,2‐dinitroethyl)‐N1‐methyl‐1H‐tetrazol‐5‐yl)‐nitramide (Tm: 76 oC, Td: 135 oC, Tp: 163 oC), N5‐(2‐fluoro‐2,2‐dinitroethyl)‐N1‐methyl‐1H‐tetrazole‐5‐amine exhibits better thermal stability (Tm: 167 oC, Td: 191 oC, Tp: 205 oC), which is superior to those of N3,N4‐bis(2‐fluoro‐2,2’‐dinitroethyl)‐1,2,5‐oxadiazole‐3,4‐diamine (LLM‐208) (Tm: 149 oC, Tp: 188 oC). They both present insensitivity towards impact but slightly sensitive to friction. It is worth noting that N5‐(2‐fluoro‐2,2‐dinitroethyl)‐N1‐methyl‐1H‐tetrazol‐5‐yl)‐nitramide shows its detonation performance approaching those of RDX. The above‐mentioned energetic performance show that they are insensitive and worth further potential applications as oxidizers, melt‐cast explosives, energetic plasticizers, or high‐performance ligands for constructing energetic coordination polymers.
