The regioselective C–H trifluoromethylthiolation of six-membered heteroaromatic compounds via nucleophilic attack of a CF3S source on the electrophilically activated six-membered heteroaromatic ring was developed. The reaction proceeds in good yield with good functional group tolerance, even on a gram-scale. The key to the successful regioselective transformation is the presence of an additive (2,

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
