Abstract

Absolute rate constants for reactions of phenoxyl radicals in solution have been compiled and evaluated from the literature. Rate constants are included for phenoxyl radicals bearing various substituents, including semiquinone radicals and radical ions, as well as aroxyl radicals derived from polycyclic aromatic compounds. The reactions tabulated include self-reactions of the radicals, reactions with other radicals, reactions with inorganic compounds, and reactions with organic compounds. A subset of the latter group includes electron transfer reactions for which the rate constants of both the forward and the reverse reaction have been measured. The radicals were generated by radiolysis, photolysis, thermolysis, or chemical reactions, and their rate constants were determined generally by kinetic spectrophotometry or electron spin resonance.
