A simple and efficient method for the preparation of α-arylthioethers through a visible-light-induced direct thiolation at α-C(sp3)-H of ethers with diaryl disulfides was developed using acridine red as a novel photocatalyst. The reactions occurred at ambient conditions and generated the corresponding products in good to excellent yields, ignoring steric effect of disulfides.

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.

One-pot synthesis of dithioacetals as well as an efficient method for oxathioacetal is reported. Additionally, some chiral auxiliaries were used to synthesize enantiomerically pure dithioacetals and oxathioacetals.
Catalyst-dependent selective synthesis of O/S- and S/S-acetals from enol ethers

, p. 3155 - 3162 (2007/10/02)
Enol ethers are reacted with mercaptanes to give the corresponding O/S- or S/S-acetals in medium to high yield. Either product can be formed selectively depending on the acid catalyst and the reaction time applied.
