Synthesis and characteristics of novel, high-nitrogen 1,2,4-oxadiazoles

Two novel high-nitrogen energetic compounds 3-azido-5-guanidino-1,2,4-oxadiazole (AOG, N% 66.65) and 3,6-bis(3'-azido-1',2',4'-oxadiazole-5'-guanyl)-1,2,4,5-tetrazine (AOG(2)Tz, N% 67.62) were synthesized and fully characterized. The thermal stability of them was evaluated with differential scanning calorimetry (DSC). AOG and AOG2Tz decomposed at 196 degrees C and 210 degrees C, respectively. They exhibit high density, favourable detonation properties, and they have low sensitivity to impact.
