Don't stand Stille : A direct heteroarylation polycondensation reaction was used for the synthesis of high‐molecular‐weight thienopyrroledione‐based polymers (see scheme) in an impressive yield (up to 96 %) and in only a few synthetic steps. This new method is an alternative to the standard Stille coupling reaction and thus avoids formation of toxic tin by‐products.
