Visible-light-induced decarboxylative sulfonylation of cinnamicacids with aryl sulfonate phenol esters enabled by the electron donor–acceptor complex is developed. The method offers a mild and green approach for the synthesis of vinyl sulfones with excellent functional group compatibility under photocatalyst and oxidant-free conditions.
