Applications of Preferential Solvation Studies to Inorganic Reaction Mechanisms.
Abstract
Preferential solvation techniques were applied to determine the composition of the coordination shell of transition metal ions. A similar approach has been used to determine relative concentrations and orientations of solvents in the solvation shell of paramagnetic complexes. A thermodynamic model of preferential solvation was devised. The preferential solvation approach was applied to two solvolysis reactions in mixed solvents. Rate data for these reactions can be readily interpreted in terms of active solvent concentrations in the solvation shell, but not in terms of bulk solvent concentrations. A similar technique was applied to a reaction in which the solvent was not a direct reactant. Again the preferential solvation approach proved useful in understanding solvent effects. Finally a set of chloride exchange rate studies with pseudo tetrahedral Co(II) complexes was made. (Author)
