Sodium-iodide-promoted nickel-catalyzed C–N cross-coupling of aryl chlorides andN-nucleophiles under visible-light irradiation

Sodium iodide facilitates halogen exchange in single nickel photocatalysis, which is critical to achieve C–N couplings of aryl chlorides and diverse nitrogen nucleophiles under visible-light irradiation in the absence of an exogenous photocatalyst.
