Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons and certain substituted derivatives thereof by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives and 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-amino-phenoxy)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.
芳香或桥式芳香烃的双(3-硝基苯氧基)衍生物是由m-二硝基苯和所述烃的双羟基衍生物以及某些取代衍生物在双极无水溶剂中存在碱的条件下进行缩合反应得到的。然后将双(3-硝基苯氧基)衍生物及其衍生物逐步还原以得到双-(3-氨基苯氧基)衍生物。这是一种用m-二硝基苯反应双羟基衍生物的新方法,因此可以制备新的双(3-氨基苯氧基)衍生物,例如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)吲哚,6,6'-双(3-氨基苯氧基)3,3,3',3'-四甲基-1,1'-螺环二吲哚和甲基取代的2,2'-双[4-(3-氨基苯氧基)苯基]丙烷。
