Initial state and transition state contributions to solvent effects in the reaction of 2,2′-bipyridyl with nickel(II) in aqueous methanol

Abstract

Kinetic and thermodynamic results show that the variation with solvent composition of the activation enthalpy for reaction of nickel(II) with 2,2′-bipyridyl in aqueous methanol represents the small difference between large destabilisations both of the nickel(II) and of the transition state (intermediate) as the proportion of methanol increases.
