offers versatile control of reaction kinetics and progress. Over the past decade, many photoactive transition-metal complexes and organic chromophores were developed to catalyze chemical transformations, enabling a myriad of reactions and compounds that were previously inaccessible via traditional synthetic methods. Here, we demonstrate the photocatalytic oxidative coupling of organic thiols using cesium
A metal‐ and reagent‐free, electrochemical cross‐dehydrogenative couplingreaction of N‐aryl‐tetrahydroisoquinolines with phosphites and indole was reported, providing an environmentally benign and simple approach for the construction of C–P and C–C.
A novel stable radical cation triarylaminiumsalt able to induce aerobic oxidative α-C–H functionalization of tertiary amines in catalytic amounts has been developed. The reaction is performed in the absence of any other additives under mild conditions and only requires atmosphere air as a sustainable co-oxidant.
A photoelectrochemical cell is able to save nearly 90% external bias input to realize activation of P–H/C–H bonds for cross-coupling hydrogen evolution as compared with an electrochemical cell.

A visible light mediated, carbonâphosphorus bond forming reaction has been developed. With the use of a readily available photoredox catalyst, α-amino phosphonates were obtained in good yields under mild reaction conditions.
