Rhodium catalysis has been extensively used for -C-H functionalization reactions, and successfully extended to -C-H functionalization. Its application to -C-H activation remains an unmet challenge. Herein we disclose the first example of such a reaction, with the Rh-catalyzed -C-H olefination of arenes. The use of a Si-linked cyanobiphenyl unit as a traceless directing group leads to highly -selective arene-olefin couplings.
铑催化已广泛用于碳氢键官能团化反应，并成功扩展到碳氢键官能团化。其在碳氢键活化方面的应用仍然是一个尚未解决的挑战。在此，我们披露了此类反应的首个实例，即铑催化的芳烃碳氢键烯基化反应。使用硅连接的氰基联苯单元作为无痕导向基团可实现高度选择性的芳烃 - 烯烃偶联反应。
