Manganese()-promoted thiocarbonylation of alkylborates with disulfides: synthesis of aliphatic thioesters

A Mn( iii )-promoted thiocarbonylation procedure toward the synthesis of thioesters has been developed. By employing easily available disulfides and potassium alkyltrifluoroborates as the starting materials, and cheap and non-toxic Mn(OAc) 3 ·2H 2 O as the promotor, a broad range of thioesters were synthesized in good to excellent yields via radical intermediates.
