THE FORMATION OF CATION-RADICALS BY THE ACTION OF CHLORINE DIOXIDE ON p-SUBSTITUTED STYRENES AND OTHER ALKENES

The Hammet plot for the reaction of ClO2 with p-substituted styrenes, the solvent effect, and the order of reacivity of several alkenes towards ClO2, indicate that the alkene-ClO2 reaction proceeds via the formation of cation-radicals.

Chlorine Dioxide as an Electron-Transfer Oxidant of Olefins

The kinetics and product studies of oxidation of eight olefins 1-8 by ClO2 in H2O in the pH range 3-7 are described.The reaction is faster as the pH decreases.At pH The order of reactivity is: (E)-stilbene > indene > β-methylstyrene > acenaphthylene > α-methylstyrene > styrene > cyclohexene > allylbenzene.A multi-stage radical-cation mechanism is proposed, in which an initial reversible protonation: is followed by an electron-transfer stage (rate-determining): The cation-radical thus produced, adds rapidly an additional ClO2 to from dioxygenated products.The chlorohydrines most likely arise from HClO additions to the olefinic double bonds, which, in turn, generate from dismutation of 2HClO2 into HClO + H+ + ClO3-.
