Visible light-driven and Iron-promoted Thiocarboxylation of Styrenes and Acrylates with CO2

The first thiocarboxylation of styrenes and acrylates with CO2 is realized by using visible light as a driving force and catalytic iron salts as promoters. A variety of important β-thioacids are obtained in high yields. This multicomponent reaction proceeds in an atom- and redox-economical way with broad substrate scope under mild reaction conditions. Notably, high regio-, chemo- and diastero-selectivity are observed. Mechanistic studies indicate that a radical pathway can account for the unusual regioselectivity.
