Abstract

Described are the syntheses of substituted enediynes and dialkynylaromatics using Pd-or Pd Cu-catalyzed cross coupling procedures. The products were then thermalized to afford the corresponding poly (p-phenylene) s, poly (1, 4-naphthalene) s, poly (benzo [c] thiophene) s, and poly (dibenzothiophene) s. Fifteen examples are provided that show the scope of the polymerization process based upon substituent patterns and cyclization ...
