Stability Study of Poly Nitro Substituted Compounds of cis-syn-cis-2,6-Dioxodecahydro-lH,5H-Diimidazo[4,5-b:4',5'-e] Pyrazine

Due to their excellent performance both in density and high detonation velocity, poly nitro substituted cis-syn-cis-2,6- dioxodecahydro-lH,5H-diimidazo [4,5-b:4',5'-e] pyrazine derivatives (2-5) attract our focus. The stabilities study showed that the sensitivity of these compounds is increasing with more nitro groups substituted. Although compound 5 with six nitro groups exhibits the most excellent detonation velocity, it is very sensitive to friction and impact. As isomer to each other, compound 2 and 3 showed not only low sensitivity but also good thermal stability with similar detonation performance to RDX and HMX. It suggests that they are potential energetic materials.
