Palladium-Catalyzed Arylation of Electron-Rich Heterocycles with Aryl Chlorides

Abstract
Palladium-catalyzed C−H activation: cheap aryl chlorides can now be used for the arylation of a wide variety of electron-rich heterocycles. The key to the success of this reaction is the use of a bulky, electron-rich phosphine ligand. No copper additives are needed.
