N , N ′-Methylenebis( N -(1,2,5-oxadiazol-3-yl)nitramide) derivatives as metal-free green primary explosives

A series of new energetic salts based on N,N'-methylenebis(N-(4-(dinitromethyl)-1,2,5-oxadiazol-3-yl)nitramide) was synthesized and fully characterized by NMR and IR spectroscopy, and elemental analysis. Their excellent vD (7995-8885 m s-1) and acceptable sensitivities (IS, 1-5 J; FS, 40-120 N) make them good candidates as metal-free green primary explosives (with the exception of 3).
