摘要:
A simple ionic liquid, 1-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.
