6-Disubstituted benzobisoxazoles have been synthesized by a highly efficient reaction of diaminobenzene diols with various orthoesters. The scope of this new reaction for the synthesis of substituted benzobisoxazoles has been investigated using four different orthoesters. The utility of these compounds as buildingblocks for the synthesis of conjugated polymers is demonstrated.

A new route for the synthesis of soluble, alkoxy‐substitutedpoly(p‐phenylenevinylene) benzobisoxazoles has been developed. The target polymers can be prepared in three steps: the Lewis acid catalyzed condensation of corresponding diamino benzene diols with triethyl orthochloroacetate, the Arbuzov reaction of the resultant benzobisoxazole, and the Horner‐Wadsworth‐Emmons polymerization of 2,5‐dido
