Peroxomonosulfate anion

In the presence of oxygen, SO generates the peroxomonosulfate anion radical (Eq. (91)) in a reaction step with a rate constant close to the diffusion controlled limiting value on the order of 1.0 x 109 to 2.5 x 109 M-1 s-1 (81,82) ... 

First-order dependence is observed with respect to both the oxidant and reductant in the oxidation of substituted anilines with peroxomonosulfate anion. Addition of acid causes retardation of the reaction. Yukawa-Tsuno correlation of the rates gave a negative reaction constant (p -1.7) and analysis of the effect of solvent in terms of Grunwald-Winstein equation (m 0.4) indicated an S -type reaction.
