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.
不要停滞不前:直接杂芳基缩聚反应用于高分子量噻吩并吡咯二酮基聚合物的合成(见方案),收率很高(高达96%),而且仅需几个合成步骤。此新方法是标准Stille偶联反应的替代方法,因此避免了有毒锡副产物的形成。
