Redox Behavior of an Organometallic Palladium(II)/Palladium(IV) System. A New Method for the Synthesis of Cationic Palladium(IV) Complexes

A new method for the synthesis of cationic Pd(IV) complexes, based on the chemical oxidation of an anionic Pd(II) metallacycle in the presence of an additional ligand, is presented. Electrochemical analysis of these compounds reveals that the stability of the +4 oxidation state is sensitive to the e...

Summary:A new method for the synthesis of cationic Pd(IV) complexes, based on the chemical oxidation of an anionic Pd(II) metallacycle in the presence of an additional ligand, is presented. Electrochemical analysis of these compounds reveals that the stability of the +4 oxidation state is sensitive to the electron-donor capability of the added co-ligand and to the steric features of the Tp‘ ligand.
