Furoxan‐Containing Energetic Salts: A Multi‐Dimensional Exploration of Synthesis, Properties, and Applications

ABSTRACT

Furoxan‐based energetic salts have drawn particular attention among explosive and propellant researchers, owing to the tendency to form versatile combinations of this high‐oxygen–containing furoxan scaffold with other selected explosive and energetic N‐hetero rings, as well as feasible approaches to derivatize the already attached substituents, and the fine‐tunable energy and safety performance of the target salts. Focusing on the advancements and trends in this field, this systematic review aims to summarize the recent information concerning the synthetic approaches toward the functionalized furoxan‐based salts and for the furoxan ring construction and the corresponding physicochemical properties and energy performances, tries to investigate the improvement of hydrogen‐rich organic bases on density, energy level and sensitivities after forming salts with acidic furoxan parent compounds, and attempts to analyze the correlation of the crystal structures of the furoxan hybrids with the physicochemical properties and explosive/propellant performances. It is expected that the present digest could serve as a perspective platform facilitating a better understanding of the current state‐of‐the‐art in this important domain and guiding the further design and synthesis of the desired furoxan‐based salts, thereby achieving the aim of developing advanced energetic materials perfectly applicable for high‐value weapons.
