Hydroarylation is an effective strategy to rapidly increase the complexity of organic structures by transforming flat alkene moieties into three‐dimensional frameworks. Many strategies have already been developed to achieve the hydroarylation of styrenes, however most of these reports examine the hydroarylation of unpolar, β‐mono‐ or β‐unsubstituted styrenes, while exploring mainly electron‐rich benzene
加氢芳基化是一种有效的策略,可通过将平面烯烃部分转化为三维框架来快速增加有机结构的复杂性。已经开发出许多策略来实现苯乙烯的加氢芳基化,然而,大多数这些报告在主要研究富含电子的苯亲核试剂的同时,研究了非极性,β-单取代或β-未取代的苯乙烯的加氢芳基化。在本文中,我们报道了一种温和而通用的催化体系,用于多取代苯乙烯和杂芳族苯乙烯的选择性加氢杂芳基化。反应的机理分析导致发现了市售的2,2':5',2''-噻吩作为关键试剂。
