Abstract

Equilibrium constants are reported for 26 light and 7 heavy phenols in terms of the usual equilibrium model of 1 : 1 complex formation. A solvation model sensitive to steric hindrance is also described. Linear correlations between log KH and ΔνOH as well as log KD and ΔνOH have been found for the interval: 30≤ΔνOH≤200 cm−1. These allow estimates on the equilibrium isotope effect.
