Carbon-halogen bond formation by the reductive elimination of Pd^II species

It is well known that Pd⁰ undergoes oxidative addition to organic halides, especially aryl or vinyl halides. In the contrast, the formation of organic halides by reductive elimination of RPd^IIX (X=halogen) has been mostly ignored until very recently. This Focus Review discusses recent developments in palladium-catalyzed carbon-halogen bond formation by the reductive elimination of RPd^IIX. These new developments have enriched the scope of palladium-catalyzed reactions, and provide a new way to construct carbon-halogen bonds.
