摘要：
An alternative approach to an AB(2) monomer, N-[3,5-bis(4-hydroxybenzoyl)benzene]-4-fluorophthalimde, 4, for hyperbranched poly(arylene ether ketone imide)s has been developed. The key steps were a para-position selective electrophilic aromatic substitution of fluorobenzene with 5-nitroisophthaloyl dichloride and a subsequent clean conversion of the aryl fluorides to phenol groups using potassium hydroxide as the nucleophile. The overall yield for the synthesis of 4 was 51.6%.
