Highly chemo- and regioselective thiocarbonylation of conjugated enzymes with thiols and carbon monoxide catalyzed by palladium complexes: an efficient and atom-economical access to 2-(phenylthiocarbonyl)-1,3-dienes

Highly chemo- and regioselective thiocarbonylation of conjugated enynes with thiols and carbon monoxide catalyzed by palladium complexes was examined as an access to 2-(phenylthiocarbonyl)-1,3- dienes. The results suggested that the reaction of 1, 3-conjugated enynes bearing a terminal triple bond with thiols and carbon monoxide catalyzed by palladium complexes gave 2-(phenylthiocarbonyl)1,3-dienes in moderate to good yields.
