摘要
The metal complex-catalyzed insertion of carbon monoxide into the C-S bond of various allylic sulfides affords thioesters in up to 88% yield. The reaction is catalyzed by various palladium complexes, with concomitant isomerization of the olefin into conjugation with the carbonyl group. In these cases, only the trans isomer was detected by H-1 NMR spectroscopy. Ruthenium complexes also catalyzed the carbonylation but the initially formed beta,gamma-thioester was not isomerized.
