A strategy has been developed for the regiospecificsynthesis of 1‐trifluoromethylisoquinoline derivatives. This strategy is enabled by a photoredoxvinylisocyanideinsertion with the help of Umemoto’s reagent. The methodology presented here provides an access to highly fuctionalized 1‐trifluoromethylisoquinolines regiospecifically under mild conditions in good‐to‐excellent chemical yields. A detailed
