We developed 2-position-selective, direct C–H trifluoromethylation, pentafluoroethylation, and heptafluoropropylation of quinolinederivatives. Regioselective transformation was achieved without derivatization of the quinolines. The reaction proceeded at room temperature with high functional group tolerance, even in gram scale. Notably, the reaction was applicable to substrates containing a functional

Feedstock aromatic compounds are compelling low-cost starting points from which molecular complexity can be generated rapidly via oxidative dearomatization. Oxidative dearomatizations commonly rely heavily on hypervalent iodine or heavy metals to provide the requisite thermodynamic driving force for overcoming aromaticstabilizationenergy. This article describes oxidative dearomatizations of 2-(h
