Palladium-catalyzed ring-opening thiocarbonylation of vinylcyclopropanes with thiols and carbon monoxide.

Palladium-catalyzed ring-opening thiocarbonylation of vinylcyclopropanes (VCPs) with thiols and carbon monoxide affords the corresponding unsaturated thioesters in moderate to excellent yields. This reaction provides a general method for the ring-opening thiocarbonylation of VCPs. It further demonstrates the utility of transition metal catalysts for the synthesis of organosulfur compounds.
