After establishing the general reaction conditions and optimizing the design of the photochemical reactor, we explored the scope and generality of the C(sp 3 )-H (hetero)arylation of light alkanes with aryl bromides in our flow reactor platform (Figure ). Notably, the utilization of flow technology facilitates the seamless execution of these reactions by harnessing flow energy in combination with back pressure regulators to apply pressure, while also enabling a continuous feed into the reactor to generate substantial quantities efficiently without having to reoptimize the reaction conditions (Figure ). Additionally, due to the straightforward setup of the reactor platform, expansion of the substrate scope can be swiftly accomplished.
