The Many Faces of FOX‐7: A Precursor to High‐Performance Energetic Materials

“…The presence of the azo (ÀN=NÀ) moiety generally imparts a high endothermic HOF to a compound; thus, the decomposition energy is largely derived from this source rather than from the fuel-oxidizer reaction. The reactions of FOX-7 with chlorine-based oxidizing reagents trichloroisocyanuric acid (TCICA) and Nchlorosuccinimide [19] were previously studied carefully by our group, and the reagents proved successful in the synthesis of the previously known dichloro substrate, 1-chloro-1,1-dinitro-2-(N-chloroamidino)ethane (8) and in the conversion of a single diamine group in FOX-7 to an azo-bridged product, (E)-1,2-bis{(E)-2-chloro-1-(chloroimino)-2,2-dinitroethyl}diazene (9).…”

X-ray powder diffraction data for acetamidinium formate C3H8N2O2, elimination of preferred orientation effect

“…Acetamidine salts are starting materials for syntheses of various nitrogen heterocycles mainly used as biologically active compounds (Gautier et al , 1975; Lobanov and Dar’lin, 2013; Re et al , 2016). In the field of energetic materials, acetamidines are starting materials for synthesis of 2,2-dinitroethene-1,1,-diamine (Latypov et al , 1998; Jalový et al , 2013), the compound with reduced sensitivity to mechanical stimuli. Main reason for the use of acetamidine in the form of salts is that free base of acetamidine is hygroscopic and rather unstable producing ammonia and acetonitrile at elevated temperatures (Crossland and Grevil, 1981) or acetamidinium carbonate in contact with air (Norrestam, 1984).…”
