Allylic carbonates were efficiently cross-coupled with triarylbismuthsunderpalladiumcatalysis. Using the optimized protocol, arylations of various allylic carbonates were carried out with triarylbismuths to afford high yields of 1,3-disubstituted propenes in regio- and chemo-selective manner. Triarylbismuths were employed as multi-coupling atom-efficient organometallic nucleophiles in sub-stoichiometric
