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

摘要

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 min -bis(3-aminophenoxy)biphenyl, 1-[4-(3-aminophenoxy)phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6 min -bis(3-aminophenoxy)-3,3,3 min ,3 min -tetramethyl-1,1 min spirobiindan, and methyl substituted 2,2 min -bis[4-(3-aminophenoxy)phenyl]propane.
