Herein, we report a Cp*Rh(III)‐catalyzed directed C−H methylation of quinolineN‐oxides at the C‐8 position using commercially available organotrifluoroborates as reagents. This method features perfect regioselectivity, relatively mild reaction conditions, and diverse functional group tolerance with good to excellent yields. Additionally, direct C‐8 arylated quinolineN‐oxides products could also be obtained
