Abstract

2,6-Bis(p-aminophenyl)benzo[l,2-rf;5,4-of']bisoxazole was synthesized with 1,2,3-trichlorobenzene as the starting material in four steps including nitration, substitution, hydrogenation and condensation with total yield of 70% . In addition, an effective purification method for 2,6-bis(p-aminophenyl)benzo[l,2-d;5,4-d'] bisoxazole was established. In comparison with other methods, there are some advantages in this method: the materials are cheap and easily available, and the product can be used as a monomer in polymerization.
