Correlation of Electrochemical Characteristics and Catalytic Activity of Rh₂(OAc)₄in the Presence of Various Phosphines

Abstract

To improve the activity of dirhodium complexes in thecatalytic reactions or biological reactions, a variety ofligands can be employed not only at the axial position butalso at the bridging position of dirhodium complexes. Sinceligands at either bridging or axial positions vary the electronicand steric properties of dirhodium complexes, investigationson appropriate ligands through the electrochemical analysishave been demanded. The electrochemical analysis ofdirhodium complexes bearing electronically different ligandshas been reported to account for the different catalyticactivity of dirhodium complexes.
