Review of the Current Synthesis and Properties of Energetic Pentazolate and Derivatives Thereof Review

Dominique R. Wozniak, Davin G. Piercey

Engineering 2020, Volume 6, Issue 9, Pages 981-991 doi: 10.1016/j.eng.2020.05.019

Abstract:

The latest member of the azole family, the pentazolate or cyclo-N₅⁻, has received increased attention since its first mass-spectral detection by Christe et al. in 2002. As it is carbon- and hydrogen-free, the pentazolate anion can release large amounts of energy while simultaneously decomposing to environmentally friendly nitrogen gas. Due to these attractive qualities, cyclo-N₅⁻ and related compounds are essential in the advancement of high-energy-density materials (HEDMs) research. This review aims to provide a consolidated report on all research done on cyclo-N₅⁻, with a focus on pentazoles as energetic materials and on their experimental synthesis. Included in this review are the following: ① the historical significance of cyclo-N₅⁻; ② precursors of cyclo-N₅⁻; ③ synthesis routes of cyclo-N₅⁻ with a focus on arylpentazole precursors; ④ factors affecting the stability of cyclo-N₅⁻; ⑤ energetic performances of current energetic cyclo-N₅⁻-containing compounds; and ⑥ future possible experimental research. This review is a comprehensive summary of the current understanding of cyclo-N₅⁻, in an effort to further understand the potential of this anion for adoption as a powerful and environmentally friendly next-generation explosive.
