A palladium-catalyzed desulfonative carbonylation of S-aryl/alkyl benzenesulfonothioates provides thioesters in good yields by SO2 extrusion and CO insertion under 1 bar of CO. Dimethylacetamide (DMAc) as solvent facilitated this desulfonative carbonylation due to its high absorbing ability of SO2.
