摘要

Ring-fused heterocycles are a promising direction for insensitive high-energy materials (IHEMs). Besides, the scalable synthesis of IHEMs is a favourable factor for practical applications. A new fused energetic pyrazolotriazine, 4-amino-3,8-dinitropyrazolo[5,1-c][1,2,4]triazine (GD-1), was synthesized via the construction of a pyrazolotriazine skeleton followed by nitration starting from the cheap and commercially available 5-aminopyrazole. GD-1 crystallizes as GD-1·2H2O (monoclinic) or GD-1·CH3OH (orthorhombic) when crystallized in acetone or methanol. GD-1 with a monoclinic crystal system has a high density (ρ = 1.83 g cm−3), good detonation performances (VD = 8895 m s−1, P = 35.4 GPa), good thermal stability (Tp = 306 °C) and low sensitivities (IS > 60 J, FS > 360 N). The good performances as well as the readily scalable synthesis make GD-1 a potential IHEM.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
