Bates, Craig G. published the artcileCopper-Catalyzed Synthesis of Vinyl Sulfides, Recommanded Product: Bromo(1,10-phenanthroline)(triphenylphosphine)copper(I), the publication is Organic Letters (2004), 6(26), 5005-5008, database is CAplus and MEDLINE.
We report a method for the synthesis of vinyl sulfides using the soluble copper(I) catalyst [Cu(phen)(PPh3)2]NO3. The desired vinyl sulfides are obtained in good to excellent yields, with retention of stereochem. This protocol tolerates a wide variety of functional groups or substrates, is palladium-free, and does not require the use of expensive or air-sensitive additives.
