, p. 3495 - 3497 (2006)
This is the first example of stereoselective synthesis of E-vinyl sulfides in water in excellent yields by hydrothiolation of aromatic alkynes with thiophenols by anti-Markonikov addition in the presence of β-cyclodextrin. This protocol tolerates a wide v
Acid/Phosphide-Induced Radical Route to Alkyl and Alkenyl Sulfides and Phosphonothioates from Sodium Arylsulfinates in Water

A newly developed aqueous system with acid and phosphide was introduced in which odorless and stable sodium arylsulfinates can in situ generate arylsulfenyl radicals. These radicals have high reactivity to react with alkynes, alkenes, and H-phosphine oxides for the synthesis of alkyl and alkenyl sulfides and phosphonothioates. The control experiments and quantum calculations are also performed to gain insights into the generation mechanism of arylsulfenyl radicals. Notably, the chemistry is free of thiol odors, organic solvents, and metals.

Herein, we report a new and solvent-free methodology for the preparation of vinyl thioethers from terminal alkynes and thiols, using magnetite (Fe3O4) nanoparticles as a recyclable catalyst. With this greener method, the desired viny
