Kinetic and thermodynamic parameters for the equilibrium reactions of phenols with the dpph. radical

Chem Commun (Camb). 2006 Aug 14:(30):3252-4. doi: 10.1039/b606322e. Epub 2006 Jun 27.

Abstract

The kinetics and energetics of the reversible reaction of phenols with the dpph. radical have been studied; steric shielding of the divalent N by the o-NO2 in dpph. seems to be the main cause of the entropic barriers of this reaction.
