Electron spin resonance studies. Part 60. Detection of radicalcations from vinyl sulphides: evidence for a cyclic structure
Abstract
Radical-cations have been detected during the oxidation of RSCHCH2(R = Et, Pri) with Cl2˙– or, ˙OH at low pH; e.s.r. parameters indicate that these possess a cyclic sulphonium structure ˙[graphic ommitted]R. Their formation from the hydroxy-adducts may involve anchimeric assistance from the sulphur atom.
