Palladium-catalyzed three-component arylcyanation of internal alkynes-with aryl bromides and K4[Fe(CN)6]

The one-pot, palladium-catalyzed, three-component coupling of aryl bromides, internal alkynes, and environmentally friendly K-4[Fe(CN)(6)] provides an efficient and direct method for the preparation of beta-arylalkenylnitriles.
