Visible‐Light Mediated Arbuzov‐Like Reaction with Thiophenols
Rajjakfur Rahaman, Akshay M. Nair, Chandra M. R. Volla
Abstract
We hereby disclose, a visible light mediated addition of sulfenyl radicals to trialkyl phosphites to access functionalized phosphorothioates. The use of cheap and readily available Eosin Y as a photocatalyst under mild energy efficient conditions bypassing the use of external oxidants forms the chief highlight of the work. The protocol is scalable and mechanistic studies indicate that the reaction proceeds through an ionic-Arbuzov like pathway from phosphoranyl radicals.
