• visible-light-induced palladium-catalyzed reactions involving halogenated hydrocarbon are mainly summarized. • SET reaction between RX and Pd(0)L was proposed in the reaction mechanism. • This review is divided into two parts according to the different substrates: C(sp2)-X based reactions and C(sp3)-X based reactions. Palladium-catalyzed chemical reactions play an important role in organic synthesis. On the other hand, visible light induced reactions can achieve many chemical transformations under mild conditions that cannot be achieved under conventional thermal reaction conditions. In this review, visible light induced palladium-catalyzed reactions involving halogenated hydrocarbon in the last three years are mainly summarized. Generally speaking, SET reaction between RX and Pd(0)L to give R radical and Pd(I)L species are proposed in the mechanism.
