Process for preparing dinitrodiazaalkanes and intermediates for this preparation process

摘要

A method of synthesis of dinitro-diaza-alkanes and intermediate products thereto from alkylamines and esters, whereby a dialkyl ester of a dicarboxylic acid is reacted with an alkylamine in an aqueous medium to form the corresponding dialkyldiamide of the dicarboxylic acid;the resulting dialkyldiamide is nitrated by means of conventional nitration agents to form the corresponding dialkyldinitroamide of the dicarboxylic acid and;the resulting dialkyldinitroamide is reacted with methylamine and/or ethylamine in an aquous medium to yield a corresponding alkylnitroamine and the dimethyldiamide and/or diethyldiamide of the dicarboxylic acid, and the alkylnitroamine is isolated from that, and the isolated alkylnitroamine is condensed in a known manner to form the dinitro-diaza-alkanes.
