Tris(ortho-tolyl) bismuth dichloride derivatives react with nucleophiles under basic conditions to give good to high yields of the C-arylated substrates. Under the same conditions, trimesitylbismuth dichloride affords only poor yields of the C-mesitylated substrates. Similar influence of the substi
