Effect of a cobalt(II) complex on the radical reaction of vinyl type sulfides. A ‘radico-catalysis’

Abstract

Vinyl type sulfides show increased radicophilicity at the β-position via the coordination to a cobalt(II) complex, and hence the balance between Smiles rearrangement and an ortho-substitution, in vinyl type sulfides having an intramolecular alkyl radical, is lost to favor the latter reaction.
