A general synthesis for the bis3,4-diaminophenoxyaryl compounds has been developed. Nucleophilic substitution of 1,2-dinitro-4-fluorobenzene by the sodium salts of aromatic diols produce tetranitro aryl ethers. Catalytic reduction of these compounds in the presence of hydrazine give the corresponding tetrafunctional amines in good yields. Polymers using these oxyarylene-amines display both good thermal stability and increased solubility in aprotic solvents such as m-cresol.
