ESR study of the effect of water on the kinetics of proton transfer and exchange in solutions of semiquinone radicals

Article abstract of DOI:10.1007/BF01558055

The interaction of 3,6-di-tert-butyl-2-hydroxyphenoxyl with triethylamine in the reaction of proton transfer is catalyzed by water.However, the rate of proton exchange with diethylamine is independent of water admixtures in the reaction medium.ESR showed that the complexing of 3,6-di-tert-butyl-2-hydroxyphenoxyl with water leads to redistribution of the spin density. - Key words: 3,6-di-tert-butyl-2-hydroxyphenoxyl; triethylamine; diethylamine; complexing; ESR.
