The present invention relates to a process to aminate electrophilic aromatic compounds by vicarious nucleophilic substitution of hydrogen using quaternary hydrazinium salts. The use of trialkylhydrazinium halide, e.g., trimethylhydrazinium iodide, as well as hydroxylamine, alkoxylamines, and 4-amino-1,2,4-triazole to produce aminated aromatic structures, such as 1,3-diamino-2,4,6-trinitrobenzene (DATB), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) and 3,5-diamino-2,4,6-trinitrotoluene (DATNT), is described. DATB and TATB are useful insensitive high explosives. TATB is also used for the preparation of benzenehexamine, a starting material for the synthesis of novel materials (optical imaging devices, liquid crystals, ferromagnetic compounds).
本发明涉及一种通过使用季铵联氮盐对芳香族化合物进行邻位亲核取代氢的方法。描述了使用三烷基联氮卤化物,例如三甲基联氮碘化物,以及羟胺,烷氧胺和4-氨基-1,2,4-三唑来产生氨基化的芳香结构,例如1,3-二氨基-2,4,6-三硝基苯(DATB),1,3,5-三氨基-2,4,6-三硝基苯(TATB)和3,5-二氨基-2,4,6-三硝基甲苯(DATNT)。DATB和TATB是有用的不敏感高爆炸物。TATB也用于制备苯六胺,这是合成新材料(光学成像设备、液晶、铁磁化合物)的起始物质。
