The subject of the present invention is a newnprocess for the synthesis of hexanitrohexaazaisowurtzitanen(HNIW), a compound useful as an energy charge innpowders, propellants and explosives.n n n This process includes a first reaction stepnof an α-β-dicarbonyl derivative with a primary aminenallowing to form a hexasubstituted derivative ofnhexaazaisowurtzitane.n n n The HNIW is then directly obtained, in a singlenreaction step, by nitration of the derivativenhexasubstituted with hexaazaisowurtzitane.n n n This process, in just 2 steps from anprimary amine, is particularly simple and not verynexpensive. |
