Three-component coupling reaction of conjugated dienes, thiols, and carbon monoxide affords an atom-economical thiocarbonylation of the dienes to give beta,gamma-unsaturated thioesters as the sole products. A catalyst system based on [Pd(OAc)(2)] and Ph(3)P showed excellent catalytic activity. The thiocarbonylation was performed under an atmosphere of carbon monoxide (400 psi) at 110 degrees C in CH(2)Cl(2)

A catalyst system based on [Pd(OAc)(2)]/(R,R)-DIOP has been found to effect asymmetric thiocarbonylation of certain prochiral 1,3-dienes to produce good yields of optically enriched beta,gamma-unsaturated thiol esters. The reaction was performed under an atmosphere of carbon monoxide (400 psi) at 110 degrees C in methylene chloride for 60 h. The asymmetric thiocarbonylation proceeded with good to excellent
