oligopyrroles are attractive precursors for both expanded porphyrin and conducting polymer chemistry. We demonstrate facile methods for synthesizing quater-, penta-, and sexipyrroles from more readily available bi- and terpyrrole intermediates. These products demonstrate stability in their brightly colored oxidized forms, while reduction using borohydride reagents gives the corresponding all-pyrrole oligomers
α,α-连接的低聚吡咯是膨胀的卟啉和进行聚合物化学的有吸引力的前体。我们展示了从更容易获得的联吡咯和三联吡咯中间体合成四,五和六吡咯的简便方法。这些产物以鲜艳的氧化形式表现出稳定性,而使用硼氢化物试剂还原则得到相应的全吡咯低聚物,该低聚物在空气中容易氧化。通过单晶X-射线衍射分析表征了氧化的四吡咯和六吡咯。
