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