The application of the Pd‐catalyzed oxidative C−H olefination of arenes, also known as the Fujiwara–Moritani reaction, has traditionally been limited by the requirement for directing groups on the substrate or the need to use the arene in large excess, typically as a (co)solvent. Herein the development of a catalytic system is described that, through the combined action of two complementary ligands
传统上,Pd催化芳烃的氧化CH H烯化反应(也称为Fujiwara-Moritani反应)的应用受到在基团上引导基团的要求或大量使用芳烃的需求的限制,通常是(共)溶剂。本文描述了一种催化系统的开发,该催化系统通过两个互补配体的共同作用,使得首次将无直接基团的芳烃用作限制试剂成为可能。反应在空间控制和电子控制的结合下进行,并且能够将这种强大的反应应用于有价值的芳烃,而这些芳烃不能过量利用。
