Compounds based on 3-amino-4-(5-methyl-1,2,4-oxadiazol-3-yl)furazan as insensitive energetic materials

“…Although we have encouraged no difficulties with the impact instability of new compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), they should be synthesized only in 1-5 millimole amounts. Therefore, best safety practices such as leather gloves and face shield are encouraged.…”

“…11 At a high temperature of 180 o C, acetamide was changed into a liquid which acts as not only a raw material but also a reaction solvent. To afford the trinitroethylamino derivatives of AMOF, we opted to use the Mannich reaction of electron deficient trinitroethylethanol 12 and AMOF under catalyzed by Lewis acid.…”

“…All the synthesized compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) were investigated by multinuclear NMR spectroscopy ( 1 H and 13 C) and IR. The 1 H and 13 C spectra of compounds 1-12 are shown in Supporting Information.…”

Reduction of 3,4-bis(4-amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazole 2-oxide

“…Relatively small number of fused polycyclic 1,2,5-oxadiazole derivatives in which one or both substituents are heterocyclic fragments have been reported [1][2][3][4][5][6][7][8][9]. There are no published data on fused tricyclic 1,2,5-oxadiazoles.…”

“…It is known that monocyclic 1,2,5-oxadiazole 2-oxides are reduced with various reducing agents to give either 1,2,5-oxadiazoles or the corresponding dioximes. It is commonly believed that the formation of dioxime is preceded by initial cleavage of the endocyclic N-O bond [5].…”
