reported methods allow access to α‐arylated selenophenes, whereas the synthesis of β‐arylated selenophenes remains very challenging. Here, the Pd‐catalysed coupling of benzenesulfonyl chlorides with selenophenes affording regiospecific β‐arylated selenophenes is reported. The reaction proceeds with easily accessible catalyst, base and substrates, and tolerates a variety of substituents both on the benzene

An expeditious synthesis of a wide range of phenanthro[9,10-b]thiophene derivatives, which are a class of polyaromatic hydrocarbon (PAH) containing a sulfur atom, is reported. The synthetic scheme involves only two operations from commercially available thiophenes, 2-bromobenzenesulfonyl chlorides and aryl bromides. In the first step, palladium-catalyzed desulfitative arylation using 2-bromobenzenesulfonyl
据报道,迅速合成了多种菲咯啉[9,10- b ]噻吩衍生物,它们是一类含硫原子的多环芳烃(PAH)。该合成方案仅涉及可商购的噻吩,2-溴苯磺酰氯和芳基溴的两种操作。在第一步中,使用2-溴苯磺酰氯进行钯催化的脱硫芳基化反应可合成噻吩衍生物,该衍生物在C4位置被含有邻溴取代基的芳基取代。然后,使用芳基溴化物进行钯催化的一锅级联噻吩分子间C5-芳基化反应,然后进行分子内芳基化反应,生成相应的菲咯啉[9,10- b噻吩在一次操作中。此外,还通过该策略设计了含有两个或三个硫原子以及硫和氮原子的多环芳烃。
