Unexpected single electron transfer catalysed cyclisation of prenyl sulphone dimer. Evidence for radical anion coupling in the outer-sphere oxidation of prenyl sulphone carbanion

Abstract

Preparative electrochemical oxidation of metallated phenyl prenyl sulphone leads to a previously unknown cyclic dimer, the formation of which has been rationalized, providing strong evidence for a radical-anion coupling mechanism in outer-sphere oxidative dimerization of α-sulphonyl carbanions.
