Abstract
Rate constants have been determined for the reaction of the tris(2,2′-bipyridyl)iron(II) cation with cyanide ion in mixed aqueous solvents containing up to 30% by volume methanol, ethanol, dioxan, and acetone, and up to 48% by volume t-butyl alcohol. Rate constants have also been determined for this reaction in aqueous solutions containing potassium, tetramethylammonium, and tetra-n-butylammonium halides. The observed reactivity trends are discussed in the light of established properties of the mixed solvents and salt solutions. In particular, the reactivity trends are compared with those forecast from consideration of the variation in estimated chemical potentials of the cyanide ion with solvent medium composition.Keywords
