A simple ionic liquid, l-methyl-3-pentylimidazolium fluoroborate, [pmIm]BF4, promotes anti-Markovnikov addition of thiols to alkynes providing (Z)- and (E)-vinyl sulfides stereoselectively. The addition of thiols to alkenes in presence of another ionic liquid, [pmim]Br proceeds through anti-Markovnikov manner, whereas the addition to vinyl ethers and acetates occurs at more electrophilic C-2 position adjacent to oxygen. The products are obtained in high yields.

The highly selective anti-Markovnikov addition of thiols to unactivated alkenes is demonstrated in water at room temperature without any additive. This is a very simple and efficient method for the synthesis of linear thioethers. Georg Thieme Verlag Stuttgart.
