Spectral, kinetics, and redox properties of the transients formed on one-electron oxidation of 4,4?-thiodiphenol: A pulse radiolysis study

Quantitative structure–activity relationships for the reaction kinetics of trace organic contaminants with one-electron oxidants

“…76,77 Organic intermediates bearing a sulfur-chlorine three-electron bond are quickly formed in these reactions, 78–80 with rate constants that are much higher than that of phenols. 40,81 Compared to previous QSARs of Cl 2 ˙ − with only para -substituted phenols using σ constants as descriptors, 82 the R 2 is lower (0.78 in this work vs. 0.95 in the literature) though more data are involved in this work. Given that descriptors mainly account for the electronic effects of substituents, Hammett constants have limitations in determining the steric hindrance effects.…”

Rate constants of dichloride radical anion reactions with molecules of environmental interest in aqueous solution: a review

“…The mechanisms of reactions were suggested as simple electron transfer. The rate constants of the sulfur compounds, 4-methylthiophenol and 4,4’-thiodiphenol, 4.7 × 10 9 and 6.9 × 10 9 M -1 s -1 , respectively, are much higher than those of phenols (Dey et al 1999 ; Mohan and Mittal 1999 ).…”
