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.

摘要： Overall, the invention provides the chemistry for the compounds and for the processes to prepare compounds derived from 1,5-diazacyclooctanes. This makes available high density, high melting point, thermally stable small and medium ring nitrogen heterocycles that may also contain N-nitro, C-nitro or other functional groups. The compounds include cyclooctanes, bicyclo octanes, propellanes and functionalized derivatives of the above compounds. The preparations can include transannular cyclizations. The materials have several applications; e.g., the polynitro compounds are energetic materials.
