- SYNTHESIS OF N-ACETOXYMETHYLNITROAMINE DERIVATIVES AND INVESTIGATION OF THEIR REACTIONS
-
A series of α,β'-substituted dialkylnitroamines were synthesized from N-2-nitrooxyethyl derivatives of N-acetoxymethylnitroamines by nucleophilic substitution reactions.The reactivity of N-chloroethyl-, N-nitroxyethyl-, and N-azidoethyl-N-acetoxymethylnitroamines in methylenebisnitroamine condensation reactions was studied.It was established that only N-chloroethyl-N-acetoxymethylnitroamines react with sulfuric acid to form N,N-chloroehtylenedinitroamines, the structure of which depends on the reaction conditions.On the basis of IR spectroscopic data it was shown that the integral intensity of the absorption bands for the antisymmetric stretching vibrations of the nitroamine group can be used for structure-group analysis of the nitroamines.
