A visible-light-induced Negishi cross-coupling is enabled by the activation of a Pd0 -Zn complex. With this photocatalytic method, the scope of deactivated aryl halides that can be employed in the Negishi coupling was significantly expanded. NMR experiments conducted in the presence and absence of light confirmed that the formation of the palladium-zinc complex is key for accelerating the oxidative addition step.
