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

N,N-disubstituted a-(xanthyl)-acetamides with an olefin on one of the substituents undergo cyclisation to a lactam by a radical chain reaction involving transfer of the xanthate group; anilides lead to the corresponding indolones.
