ABSTRACT:
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.
