To improve the detonation performance, 1,2,4,5‐tetrazine and [1,2,4]triazolo[4,3‐b][1,2,4,5]tetrazine N ‐oxide explosives were prepared by oxidation reaction with trifluoroacetic peroxide acid. Thus, four compounds were synthesized and characterized. Among them, 3,6‐bis((3‐nitro‐1,2,4‐oxadiazol‐5‐yl)amino)‐1,2,4,5‐tetrazine 1‐oxide ( TDOX ) showed good detonation performance ( D , 8926 m s −1 ; P , 34.8 GPa) and favorable thermal stability ( T d , 228 °C, onset). All compounds featured mechanic insensitivities ( IS >40 J, FS >360 N).
