Electron spin resonance studies. Part XLVIII. Radicals derived from organic sulphites and related compounds

Abstract

The reactions of organic sulphites and some related compounds with the hydroxyl radical have been investigated by e.s.r. spectroscopy in conjunction with a flow-system technique. There is evidence for a rapid reaction with sulphites, probably at sulphur, which yields an alkoxyl radical; this can be trapped by the nitromethane aci-anion, but otherwise is rapidly transformed into the isomeric 1-hydroxyalkyl radical.
