Abstract
AbstractA mild, efficient and straightforward visible‐light‐driven method has been developed to construct 1,2‐diarylvinyl sulfides under catalyst‐ and additive‐free conditions. The formation of small amounts of thiyl radicals under visible light irradiation allows the synthesis of 1,2‐diarylvinyl sulfides in good yield with an excellent functional group tolerance.
Highlights
The addition of thiols to alkynes is one of the most straightforward methods for obtaining vinyl sulfides used as a potential building block for the synthesis of many polymeric materials, natural products and synthetic reagents

Thiols add to terminal alkynes under radical conditions to afford anti-Markovnikov type vinyl sulfides with excellent regioselectivity, but as mixture of geometric isomers
