Summary: Tailored monomers based on the activated esters of 2,5‐dibromo‐benzoic and 2,5‐dibromobenzene‐1‐sulfonic acids or 3‐substituted 2,5‐dibromothiophene suitable for the Suzuki, Yamamoto or Grignard metathesis (GRIM) coupling reactions were synthesized and characterized by the melting point, elemental analysis, 1 H NMR, FT IR, and TLC. The Horner‐Wadsworth‐Emmons reaction was utilized for the preparation of 3‐(arylvinyl)‐2,5‐dibromothiophenes and the 4‐nitrophenol or N ‐hydroxysuccinimide for the preparation of activated esters. A monomer with β ‐diketone active structure was prepared and characterized as well.
