Radical, One-Step Approach to o-Chlorophenyl Thioethers from Xanthates. A Rapid Access to Vinylsilanes

Xanthates have been readily converted into o-chlorophenyl thioethers using a one-step procedure conducted under radical conditions. In some selected cases, these aryl thioethers were successfully oxidized to the corresponding sulfoxides and sulfenic acid elimination afforded the corresponding vinylsilanes.
