Abstract
This study presents the synthesis of ethyl 5‐[(nitrooxy)methyl]isoxazole‐3‐carboxylate (EEIN) and isoxazole‐3,5‐diylbis(methylene) dinitrate (IDN). These compounds, each derived from 5‐(hydroxymethyl)isoxazole‐3‐carboxylate, were fully characterized and their explosive sensitivity properties were determined. EEIN was isolated as a solid material with a relatively low melting temperature and IDN was isolated as a liquid with excellent energetic performance properties. In addition, we report the molecular structure of ethyl 5‐[(nitrooxy)methyl]isoxazole‐3‐carboxylate as determined by single‐crystal X‐ray diffractometry. These compounds possess promising properties as plasticizing ingredients in propellant formulations.
