Bis(3-aminophenoxy) aromatics and method of preparing the same

Abstract From the Canadian patent

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 …
