A New Synthetic Route for 3,3′-Bis(fluorodinitromethyl)difurazanyl Ether (FOF-13) and Its Energetic Properties

Energetic 4,4′‐Oxybis[3,3′‐(1‐hydroxytetrazolyl)]furazan and Its Salts

“…The synthetic route to the target compounds is outlined in Scheme2.3 ,3'-Dicyanodifurazanyl ether (1)w as the starting material,w hich was prepared according to ap rocedure reported in the literature. [11] Treatmento f1 with aqueous hydroxylamine gave hydroximoylamine (2), whichw as treated with sodium nitrite in dilute HCl to produce 3.C ompound 3 was reacted with sodium azide in am ixture of ethanol and water at room temperature to form 4,w hich was not isolated because it was likely to be very sensitive. After extracting the reaction mixture with ethyl ether,t he organicp hase was dried over magnesium sulfate and gaseous HCl was bubbled into the solution until it was saturated at 0 8Ca nd then stirred overnight.…”

“…Asian J. 2016,11,[3113][3114][3115][3116][3117] www.chemasianj.org with cations 6-10 were prepared. All compounds were fully characterized and their energetic properties were studied.…”

“…Compound 3 [11] (0.93 g, 3.0 mmol) was dissolved in ethanol (10 mL) and the solution was cooled to 0 8C. Then as olution of sodium azide (0.49 g, 7.5 mmol) in water (5 mL) was slowly added.…”

Synthesis and Characterization of 3‐(5‐(Fluorodinitromethyl)‐1H‐1,2,4‐triazol‐3‐yl)‐4‐nitrofurazan: A Novel Promising Energetic Component of Boron‐based Fuels for Rocket Ramjet Engines

“…Moreover,C FHNO-oxidizer/metalfuel combination offersapropellant performance advantage of producing al arger number of moles of gas per gram, more moles of more-volatile, lower-molecular-weightc ombustion products (e.g.,AlOF vs. Al 2 O 3 or BOF vs. B 2 O 3 ). [9] While many potent energetic furazans bearing fluorodinitromethyl moiety,C (NO 2 ) 2 F, have been reported, [10] very few syntheses of energetic 1,2,4-triazolesw hich incorporate this moiety at ac arbon atom of the ring have been described [5b, 11] ( Figure 1). The design and synthesis of new oxygen-rich energetic compounds with high density and improved performance has been the focus of recent studies in our group.…”

Theoretical design and prediction of properties for dinitromethyl, fluorodinitromethyl, and (difluoroamino)dinitromethyl derivatives of triazole and tetrazole

“…[19][20][21][22][23] Molecules in which the uorodinitromethyl moiety [-CF(NO 2 ) 2 ] is attached via a carbon atom to an aliphatic, aromatic, or heterocyclic skeleton have been revealed to have useful energetic properties and stabilities. 22,[24][25][26] Notably, the incorporation of the (diuoroamino)dinitromethyl moiety [-C(NF 2 )(NO 2 ) 2 ] is another effective tool for constructing energetic compounds, as it provides a high energy content while maintaining a high density and acceptable thermal and processing properties. 27 In view of these ndings, it is observed that the multi-nitro functional groups have a great development from simple to complex (Scheme 1).…”
