Rate constants for the reaction of halogenated alkylperoxyl radicals with iodide: influence of substituents, solvent polarity, and proton concentration
polarity of solvent mixtures and electronegativity of the substituents at the α-C atom of the peroxyl radicals. They strongly depend on all these variables, with the actual numbers covering a range from 3 × 105 to 7.0 × 108 M−1 s−1. A good linear relationship is obtained between logk and the dielectric constant of the solvent mixture. Within a particular solvent mixture the rateconstants depend strongly
