A simple Brønsted acid catalyzed tandem reaction, including intermolecular nucleophilic addition, substitution and intramolecular cyclization, in a one-pot manner is described. Thirty two 2-indolyl substituted carbazoles are generated in good to excellent yields. Based on this tandem reaction strategy, the poly(1,4-carbazole) is prepared for the first time. Preliminary studies indicate that the poly(1
描述了一种简单的布朗斯台德酸催化串联反应,包括以一锅法方式进行的分子间亲核加成,取代和分子内环化。以良好至优异的产率产生了三十二个2-吲哚基取代的咔唑。基于这种串联反应策略,首次制备了聚(1,4-咔唑)。初步研究表明,聚(1,4-咔唑)具有良好的热稳定性和光学性能。
