A series of ruthenium-arene complexes with the general formulas (C6H6)RuCl2L and (C6H6)RuClL2+ (L = phosphine- and pyridine-based ligands) have been studied electrochemically in order to determine the rate at which the arene ring is displaced when the metal is oxidized from Ru(II) to Ru(III) in the presence of a coordinating solvent. The reactions were followed using cyclic voltammetry, simulation software was used to determine the rate of arene ring displacement, and 1H NMR was used to analyze displacement reaction intermediates and products. The electrochemical properties of these compounds and the identification of possible intermediates in the displacement reaction will be presented, and the factors that affect the displacement of the arene ring in these complexes will be discussed.
