Pulse radiolysis studies XI. Protonation reactions of aromatic anions in some aliphatic alcohols

Abstract

The protonation reaction of aromatic anion radicals in the aliphatic alcohols, [Formula: see text]has been investigated by the pulse radiolysis method. Activation energies for this reaction have been determined for the anthracenide anion and diphenylide anion in methanol, ethanol, and isopropanol, and for the naphthalenide anion in isopropanol. Absolute rate constants have been determined as well for the phenanthrenide, o-terphenylide, and m-terphenylide anions in isopropanol at 25 °C. The values for the rate constants, activation energies, and the pre-exponential factors are given. Those properties of the system which determine the kinetics are briefly discussed.
