The threefold cross-coupling of triarylbismuthreagents with 4-chloro-3-formylcoumarins furnished the corresponding 4-aryl-3-formylcoumarins in a chemoselective manner with high yields under Pd-catalyzed conditions. This method was successfully applied to electronically different triarylbismuthreagents and 4-chloro-3-formylcoumarins preserving the 3-formyl group in the coumarin scaffold.
