Investigation of the Mechanism of Palladium-Catalyzed Reactions by Electrochemistry
A new mechanism for Heck reactions catalyzed by a mixture of Pd(OAc)2 and triarylphosphines has been established by means of electrochemical techniques. The complex ArPd(OAc)L2 is found to be a key intermediate which reacts with the olefin. These results emphasize the role of the acetate ions present in Pd(OAc)2, precursor of the palladium(0) catalyst.
