Abstract:
We report pyrrole-based zwitterionic energetic material 3-diazo-2,4-dinitropyrrole (DDNPy), obtained via an efficient nitration-amination-diazotization sequence. The compound exhibits remarkable thermal stability (Td = 190 °C) and superior detonation performance (Dv = 7.94 km s-1; Dp = 27.2 GPa). Crystallographic and Hirshfeld analyses reveal a compact, strongly bound lattice with balanced sensitivities. These combined attributes identify this zwitterionic molecule as a promising metal-free candidate for environmentally benign next-generation primary explosives.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
