Thiol–ene/oxidation tandem reaction under visible light photocatalysis: synthesis of alkyl sulfoxides†
The photocatalyzed synthesis of sulfoxides from alkenes and thiols has been carried out using Eosin Y. This is a metal-free method which uses a low catalyst loading, atmospheric oxygen as the oxidant, and visible light conditions (green light). A mechanism has been proposed that is consistent with the experimental results.
