Synthesis and structure of dinitroazofurazan

Abstract

The synthesis of dinitroazofurazan (3) was achieved from readily available diaminofurazan (6) in two steps and 20% overall yield. The structure of the energetic material 3 was unequivocally confirmed by X‐ray crystallography and found to have a crystal density of 1.742 g/cm3.

“…DAF was a gift from the Thiokol Corporation and the Air Force Research Laboratory (AFRL), crude ANAF was a gift from Dean Woolery of AFRL, and DAHzF was a gift of Dr. Mike Hiskey of Los Alamos National Laboratory. Literature methods were used to prepare ANF (15) , DAAF (15) , DNAzF (33) , DAAzF (38) , and DNAF (38) . DNHzF is a new compound.…”

Chromophoric macrocycles from the oxidation of bis(aminofurazanylic) ethers of 1,2‐diols

“…However, only trans-azofurazans were isolated and characterized by X-ray analysis at present [27,30,32,33,42,44,45]. Most probably, in the solid state these conformers are most stable; that is for solutions, mutual conformational changes are possible, which makes identification of the conformers more difficult.…”

Synthesis of difurazanyl ethers from 4,4?-dinitroazoxyfurazan

“…123-124ЊC, (m.p. 125ЊC [23a], 122.5ЊC [29], 120ЊC [10]). The third fraction, 3-amino-4-(4-nitrofurazanyl-NNO-azoxy)furazan (22) was obtained as yellow crystals, m.p.…”

“…Nitrofurazans are well known for their high energy contents [1][2][3][4][5][6][7][8][9][10], and the methods of synthesis of these useful heterocycles have been reviewed by Boyer [11] and Sheremetev [12].…”
