Synthesis and Characterization of N3-(2,2,2-Trinitroethyl)-1,2,4-Oxadiazole-3,5-Diamine
The reaction of 1,2,4-oxadiazole-3,5-diamine with 2-fluoro-2,2-dinitroethanol or 2,2,2-trinitroethanol was studied. Only the 3-amino group was found to be reactive and underwent efficient Mannich-type condensation with 2,2,2-trinitroethanol, while only trace amounts of product from condensation with 2-fluoro-2,2-dinitroethanol were formed. N3-(2,2,2-Trinitroethyl)-1,2,4-oxadiazole-3,5-diamine was fully characterized, and its crystal structure and explosive sensitivity properties were determined. Calculated performance properties show that the product is a promising RDX-like material with a higher oxidizing potential.
