Synthesis and Characterization of Bisnitrofurazanodioxadiazine (BNFOZ)

Synthesis and Characterization of BNFF Analogues

“…When BAFF R was treated with TFAA/60% H 2 O 2 / H 2 SO 4 or ammonium persulfate/60% H 2 O 2 /H 2 SO 4 , the same reaction condition of BAFF oxidation, BNFF R was not given. 5,6 It seemed that the lower stability of furazan compared to furoxan, made BAFF R readily decomposed under strong acidic and oxidative conditions. Secondly, we examined the selective reduction of nitro groups via hydrogen transfer reactions.…”

Synthesis and Characterization of an Energetic Compound (E)-4,4'-bis(tert-Butyl-N,N,O-azoxy)-3,3'-diazenofurazan

“…Compounds based on pentaheterocyclic furazan (1,2,5oxadiazole) composed of two nitrogen atoms and one oxygen atom had been widely applied into the fields of medicine 1,2 and war industry and civil fields [3][4][5][6][7][8] . Owing to their high nitrogen content, low vulnerability, good oxygen balance, positive heat of formation, high density caused by planarity of the ring, furazan-based compound has been recognized as a promising candidate for the design and synthesis of high energetic materials (HEM) [9][10][11][12] .…”

Synthesis, Crystal Structure, and Thermal Behavior of 3‐(4‐Aminofurazan‐3‐yl)‐4‐(4‐nitrofurazan‐3‐yl)furazan (ANTF)

“…

1IntroductionNitro and aminof urazan compounds have gaineds ubstantial interest due to their great variety of possible structures, physical and chemical properties, and their application as high density energeticm aterials [1,2].A so ne of the high energy materials, at ypical furoxan derivativei s3 ,4-bis(4'-nitrofurazan-3'-yl)furoxan (DNTF). DNTF is mainly used in melt cast explosives because of its high nitrogen content, good oxygen balance, and high energy density [3][4][5].U nfortunately,t wo main problems still exist:i ts melting point (110 8C) reaches the upperl imit for the melting point of melt caste xplosives, which is of inconvenience for the casting procedure. Secondly,i th as ah igher impact sensitivity (IS) than other melt-cast explosives such as TNT,w hich prevented it from aw ide range of applications [6,7].A number of attempts has been made to overcomet hese drawback, the first way was to form eutectic explosives with other explosives, and the second way was to modify its structure to develop new derivatives.

“…As one of the high energy materials, a typical furoxan derivative is 3,4-bis(4'-nitrofurazan-3'-yl)furoxan (DNTF). DNTF is mainly used in melt cast explosives because of its high nitrogen content, good oxygen balance, and high energy density [3][4][5]. Unfortunately, two main problems still exist: its melting point (110 8C) reaches the upper limit for the melting point of melt cast explosives, which is of inconvenience for the casting procedure.…”
