hydrothiocarbonylation of unsaturated carbon–carbon bonds at room temperature with high chemo- and regioselectivity. The reaction is applicable to the synthesis of cysteine-derived thioesters, thus allowing chemical modification of cysteine-containing peptides. Decarboxylation of OAM proceeds through oxidative addition of Pd(0) to the acyl–S bond, which accounts for the very mild reaction conditions

reagent, is reported herein as a synthetic equivalent of thioester for palladium-catalyzed decarboxylative hydrothiocarbonylation of vinylarenes to achieve both branched and linear regioselectivity. The reactions provided user-friendly synthetic methods for preparation of α- or β-arylated propionic acid thioesters from vinylarenes without directly handling toxic carbon monoxide and odorous thiols.
