C–H functionalization of electron-deficient heteroarenes using commercial unactivated alkyl halides through reductive quenching photoredoxcatalysis was developed. Mainstream approaches rely on the use of an excess of strong acids that result in regioselectivities dictated by the innate effect of the protonated heteroarene, leaving the functionalization of other carbons unexplored. We report a mild
