The addition of polyfluoroalkanesulfenic acids to alkenes

• In the addition of polyfluoroalkanesulfenic acids to various carbon–carbon double bonds has been investigated.
• Both Markovnikov adduct and anti-Markovnikov adduct could be obtained with different alkenes.
• The excellent regioselectivity was obtained.

The addition of polyfluoroalkanesulfenic acids, in-situ formed from various imines, to CC double bond was investigated. Both Markovnikov adduct and Michael-type adduct could be obtained with different alkenes. A series of sulfoxides were synthesized with excellent regioselectivities under mild conditions.
