Heterogeneous metallaphotocatalytic chemical transformations employing a recyclable catalyst are highly desirable for organic synthesis. However, the rational design and controlled preparation of well-defined, site-isolated metal/photo bifunctional heterogeneous catalysts to achieve this goal remain significant challenge. In study, we demonstrate covalent attachment homogeneous molecular MnSalen complex (where Salen = N,N′-bis(salicylidene)ethylenediamine) onto surface graphitic carbon nitride (CN) via an amide bond visible-light-driven chloro- azido-fluoroalkylation unactivated alkenes. The linkage between CN not only facilitates electron delocalization enhances light-harvesting capabilities photosensitizer but also exerts proximity effect that markedly ability Mn sites capture alkyl radical intermediates during reaction process. A diverse set alkenes could be efficiently azido-fluoroalkylated their corresponding difunctionalized products in moderate high yields with good functional group compatibility. Furthermore, practicability protocol is illustrated through late-stage diversification various bioactive compounds pharmaceuticals. Notably, integrated photocatalyst demonstrates stability can recycled at least 10 times without loss activity selectivity.
