ortho-heteroarylation of aromatic carboxylic acids with various heteroarenes has been developed through Rh(III)-catalyzed two-fold C–H activation, which exhibits a wide substrate scope of both aromatic carboxylic acids and heteroarenes. The use of naturally occurring carboxylic acid as the directing group avoids troublesome extra steps for installation and removal of an external directing group.
芳香族羧酸与各种杂芳烃的高选择性脱羧邻杂芳基化反应是通过Rh(III)催化的2倍C–H活化而开发的,这显示了芳香族羧酸和杂芳烃的广泛底物范围。使用天然存在的羧酸作为导向基团避免了麻烦的用于安装和除去外部导向基团的额外步骤。
