The perfluoroalkylthiolation reaction of thiols with perfluoroalkanesulfenic acids

The perfluoroalkylthiolation reactions of thiols with perfluoroalkanesulfenic acids were achieved without adding any additives, giving a series of unsymmetric disulfides in good to excellent yields. After simple removal of solvent from reaction system under reduced pressure, most products could be obtained with high purity. The reaction tolerates both aryl and alkyl thiols and has advantages such as easy-to-handle, additive-free and simple separation procedure.
