Rate constants for the reactions of ClO2, NO2, and SO3(1-) radicals with several substituted phenoxide ions have been measured by pulse radiolysis.They vary from the immeasurably slow (4) to almost diffusion-controlled rates (>109 M-1 s-1) and depend on the redox potentials of the phenoxide ions and the inorganic radicals.With the weak oxidant SO3(1-) reverse reactions were observed in certain cases; i.e., the phenoxyl radical oxidizes sulfite ions.An attempt is made to correlate the rate constants with Hammett's substituent constants and the results are compared with those obtained previously for the reactions of various inorganic radicals with phenols and phenoxide ions.

Tert-butoxy radicals generated in the photodecomposition of di-tert-butyl peroxide react efficiently with phenols to yield the corresponding phenoxy radicals.Typical rate constants in benzene at 22 deg C are 3.3x108 and 1.6x109 Msup
