Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives obtained are successively reduced to afford bis-(3-aminophenoxy) derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4'-bis(3-aminophenoxy)biphenyl, 1-[4-(3-aminophenoxy) phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6'-bis(3-aminophenoxy)-3,3,3',3'-tetramethyl-1,1'spirobiindan, and methyl substituted 2,2'-bis[4-(3-aminophenoxy) phenyl)propane.
芳香族或桥接芳香族烃的双(3-硝基苯氧基)衍生物是由间二硝基苯和上述烃的二羟基衍生物在碱存在下,在双极性非丙烷溶剂中通过缩合反应制得的。得到的双(3-硝基苯氧基)衍生物被连续还原,得到双(3-氨基苯氧基)衍生物。这是一种将二羟基衍生物与间二硝基苯反应的新方法,因此可以制备新型双(3-氨基苯氧基)衍生物,如 4,4'-双(3-氨基苯氧基)联苯、1-[4-(3-氨基苯氧基)苯基]-1,3,3-三甲基-6-(3-氨基苯氧基)茚,6,6'-双(3-氨基苯氧基)-3,3,3',3'-四甲基-1,1'螺双茚,以及甲基取代的 2,2'-双[4-(3-氨基苯氧基)苯基]丙烷。
