Synthesis and Characterization of Some New Melt‐Castable Explosive Materials

摘要

The efficient and scalable synthesis of 3,3′‐biisoxazole‐4,4′,5,5′‐tetrakis(methyl nitrate) and itsenergetic properties are described. The synthesis features a metal‐free [3+2] cycloaddition of an electronrichinternal alkyne and a nitrile oxide by simple heating, without using halogenated solvents. The materialhas favorable sensitivity properties, and its energetic properties point toward its potential as a nitrateplasticizer and highly explosive material.
