of unactivated alkenes is an indispensable mean in synthetic chemistry. Given that addition of electrophilic species into alkenes intrinsically follows the Markovnikov rule, a regioselectivity switch presents a major challenge. Herein, we present a visible-light-promoted strategy for the selective anti-Markovnikov hydrooxygenation of unactivated alkenes. Therefore, an innovative reagent was carefully
