An effective method has been developed for Rh(III)‐catalyzed direct vinylation of arenes to give functionalized styrenes, using vinyltriethoxysilane as a convenient and inexpensive vinyl source. A wide variety of substrates, including 1‐aryl‐2‐pyrrolidinones, anilines, benzamides and ketones, were compatible with this reaction. Moreover, this method can be applied to the two‐step synthesis of functionalized
已开发出一种有效的方法,可使用乙烯基三乙氧基硅烷作为方便,廉价的乙烯基来源,对Rh(III)催化的芳烃进行直接乙烯基化,以生成官能化的苯乙烯。此反应兼容多种底物,包括1-芳基-2-吡咯烷酮,苯胺,苯甲酰胺和酮。而且,该方法可以应用于功能化吲哚的两步合成。机理研究表明该反应可能通过氧化性Heck /去甲硅烷基化途径进行。
