Two ether-linked nitramines explosives have been synthesized. The reactivity of ether-linked nitramines has been probed and it was found that with heating, it is possible to perform a ring contraction to a methylene-linked nitramines that may be suit

A new synthetic protocol for the preparation of 3,3-disubstituted cyclopropenes from the corresponding bromocyclopropanes via a base-assisted 1,2-elimination has been developed. Employment of catalytic amounts of 18-crown-6 in ethereal solvents allow

A new, spherical morphology of tetranitroglycoluril (TNGU) has been prepared from the solvent, anti-solvent interaction of nitric acid and dichloromethane. This spherical morphology is significantly less sensitive to impact, friction, and static disc

A highly diastereoselective formal nucleophilic substitution of bromocyclopropanes with oxygen- and nitrogen-based nucleophiles was demonstrated. The reaction proceeds via a base-assisted dehydrohalogenation producing a cyclopropene intermediate, whi
