The synthesis of a new energetic 1,2,4‐triazole compound bearing nitrofurazanyl and fluorodinitromethyl units, which may find use as a component for rocket ramjet engines (RRE), is described. The target product was prepared in a four‐step process applying oxidation/nitration/decarboxylation/fluorination reactions and is fully characterized. Its density and structural features were uniquely determined by X‐ray analysis. It is shown that replacing HMX with the compound of this study in boron‐based fuels gives an increase in energy. Energetic materials: A four‐step process based on oxidation/nitration/decarboxylation/fluorination reactions was utilized for the preparation of an high‐energy compound combining 1,2,4‐triazole, nitrofurazanyl and fluorodinitromethyl units. This compound has potential as a fuel component for rocket ramjet engines, providing a more complete combustion of boron.
