Fluorination and nitration of bis(2,2,2-trinitroethyl)urea has given the novel N-fluoro-bis(2,2,2-trinitroethyl)urea and N-nitro-bis(2,2,2-trinitroethyl)urea.The thermal decomposition rates and parameters for bis(2,2,2-trinitroethyl)urea and its derivatives have been found, and the standard enthalpies of combustion, and the standard enthalpies of formation of these compounds calculated there from, have been determined. Keywords: fluorination, nitration bis(2,2,2-trinitroethyl)urea, kinetics of thermal decomposition, heat of combustion, enthalpy of formation.

Herein, the mono-trinitroethyl-substituted product of 3,5-diamino-1,2,4-oxadiazole (1) was easily obtained. However, the bis(trinitroethyl)- or nitramino-substituted product of 1 in the presence of acid was not obtained, as expected, due to an interesting ring cleavage of the 1,2,4-oxadiazole ring. Compound 1 and the ring cleavage products 2 and 3 exhibit good energetic performance and acceptable sensitivities.

scheme or table, p. 21 - 23 (2012/04/10)
Based on Henry and Mannich reactions of polynitroalkanes for the first time implemented in ionic liquids, ecologically pure and safe methods for the synthesis of polynitro alcohols and N-2,2,2-trinitroethyl derivatives of low basic amino compounds (urea, acetamide, 4-amino-3-methylfuroxan) have been elaborated.
