Oxidative addition and reductive elimination are the central steps in new palladium‐catalyzed chemistry that forms C–N and C–O bonds in arylamines and ethers. In the potential mechanism shown on the right the amine is formed by reductive elimination from a four‐coordinate, 16‐electron amido aryl complex. The use of a chelating ligand such as 1,1′‐bis(diphenylphosphanyl)ferrocene (DPPF) reduces the occurrence of the competing β‐hydrogen elimination. X=Br, I; R, R′=alkyl, aryl.
