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

Mario C Foti1, Carmelo Daquino.   

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.
