Procedure

Equimolar amounts of 4-nitrobenzil and 4-phenoxyphenol are reacted in the presence of potassium t-butoxide under conditions described in Example 56 paragraph (d) to form 4-(phenoxyphenoxy)benzil. A polyquinoxaline terminated by aromatic groups which are susceptible to aromatic electrophilic substitution is synthesized by the reaction of p-BOB from Example 56, -(phenoxyphenoxy)benzil and 3,3',4,4'-tetraaminobiphenyl in m-cresol The resulting polyquinoxaline polymer is isolated.
