摘要:
This invention involves a new class of compounds, certain geminal-dinitro-substituted heterocycles, including geminal-bis(difluoramino)-substituted heterocyclic nitramines and the production thereof. More specifically, this invention involves the production of 3,3-bis(difluoramino)octahydro-1,5,7,7-tetranitro-1,5-diazocine (TNFX), which may be formulated into explosives and propellant oxidizers. The method of making a 3,3-bis(difluoramino)octahydro-1,5,7,7-tetranitro-1,5-diazocine comprises reacting a hexahydro-7,7-dinitro-1,5-bis(nitrobenzenesulfonyl)-1,5-diazocin-3(2 H)-one with a difluoramine source to produce a 3,3-bis(difluoramino)octahydro-7,7-dinitro-1,5-bis(nitrobenzenesulfonyl)-1,5-diazocine and reacting said 3,3-bis(difluoramino)octahydro-7,7-dinitro-1,5-bis(nitrobenzenesulfonyl)-1,5-diazocine with a highly reactive nitrating reagent in the presence of a strong Lewis acid, such as antimony pentafluoride, boron triflate or boron fluorosulfonate.
