Abstract

The synthesis of 2,2’,5’,2”-terthienyl (IV) is reported. A key intermediate in this synthesis was 1,4-di(2-thienyl)-1,4-butanedione (III), which was prepared from trimethylsilyl enol ether (II) of 2-acetylthiophene (I). Corresponding furyl derivatives were also synthesized by the similar procedure.
