Abstract

Continuous-flow EPR studies of the reaction between CeIV and the peroxymonosulphate anion HOOSO3– at low pH enable the isotropic EPR spectrum of SO5˙– to be characterized, and provide kinetic information on the formation and reaction of this radical. Alkylperoxyl radicals (RO2˙) detected when the reaction is carried out in the presence of alkenes (e.g. methyl methacrylate) are shown to arise from reactions of SO4˙–(derived from self-reaction of SO5˙–) with the alkene, and subsequent addition of oxygen (also formed from SO5˙–).
