Formate‐Mediated Synthesis of β‐Hydroxysulfides from Olefins and Thiosulfonates via EDA Complex Strategy under Visible Light Irradiation in Air

Abstract

Comprehensive SummaryA visible‐light‐induced and efficient one‐pot synthesis of β‐hydroxysulfides from olefins, thiosulfonates and HCOOCs using an EDA complex strategy under air atmosphere at room temperature has been disclosed. A plausible radical involved mechanism is proposed. During the reaction process, formates play a crucial role: first, as donors in the EDA complex; second, as providers of the hydrogen source; and third, by generating CO2•– to reduce peroxide intermediates, leading to the formation of β‐hydroxysulfides. In contrast to the previously reported thiol‐oxygen co‐oxidation reactions, this simple and sustainable approach features mild reaction conditions, operational simplicity, odorless and excellent functional group tolerance.
