Triarylbismuth compounds have been cross-coupled as atom-efficientmulticoupling organometallic nucleophiles with 4-bromo- and 4-(trifluoromethylsulfonyloxy)coumarins underpalladiumcatalysis conditions. These reactions afforded an array of 4-arylcoumarins in high yields. The general palladium protocol has been demonstrated to be efficient for the coupling of both bromide and triflate derivatives
