We describe here a visible light photochemical approach for practical helicene functionalization at very mild reaction conditions. The photochemical reactions allow the regiospecific and innate late-stage functionalization of helicenes and are easily executed either via the activation of C(sp2)–Br bonds in helicenes using K2CO3 as inorganic base or direct C(sp2)–H helicene bond functionalization under oxidative photoredox reaction conditions. Overall, using these transformations six different functional groups are introduced to the helicene scaffold via C–C and four different C–heteroatom bond-forming reactions.
