  Electrochemical Characterization of Equilibria Involving Catalyst Precursors:  Cyclic Voltammetry of Labile Organorhodium Complexes in Coordinating Solvents

  摘要：

  Cyclic voltammetry (CV) has been used to characterize equilibria between [Rh(COD)(2)](+) and [Rh(COD)(solv)(2)](+), where COD = cyclooctadiene and solv = acetone, 2-butanone, or acetonitrile. In donor solvents the reversible one-electron reduction of [Rh(COD)(2)](+/0) obeys the voltammetric diagnostics for a chemical reaction preceding electron transfer (a CE mechanism), The cathodic current for this wave is monitored as a function of CV scan rate in order to derive both equilibrium and rate constants for addition and elimination of COD from the metal center. The rate of addition of COD to [Rh(COD)(solv)(2)](+) is not significantly solvent-dependent, whereas elimination of COD from [Rh(COD)(2)](+) is about 4400 times faster for solv = CH3CN than for either acetone or 2-butanone. The exchange reaction is apparently associative in both directions, following a 16e(-)/18e(-) pathway. Electrochemical methods are shown to provide a useful alternative to optical and magnetic resonance methods for the characterization of organometallic systems with labile ligands.
