Synthesis of 3-(3,5-dinitropyrazol-4-yl)-4-nitrofurazan and its salts
摘要:
AbstractThe annulation reaction of vinamidinium salt containing nitrofurazanyl moiety at the β‐position gives access to the corresponding pyrazole. At nitration, two nitro groups were installed to the pyrazole ring. The synthesized 3‐(3,5‐dinitropyrazol‐4‐yl)‐4‐nitrofurazan13is strong NH acid and a new family energetic salts was prepared by direct neutralization with high nitrogen bases. Compound13crystallizes in the monoclinic space groupP21/c, and charaterized by high density of 1.979 g/cm3(at 100 K). J. Heterocyclic Chem., (2012).
