On the unexpected cathodic electrodimerization of phenyl vinyl sulphone in slightly protic media: the formation of 1,4-bisphenylsulphonylbut-2-ene
Abstract
Phenyl vinyl sulphone exhibits unusual cathodic behaviour in organic media containing a small excess of a proton donor such as acetic acid or phenol; both the saturated sulphone and an unsaturated dimer are isolated, the formation of which may be explained by hydrogen atom transfer between the organic free radicals formed at the interface.
