A palladium-catalyzed addition of potassium aryltrifluoroborates to aliphatic nitriles leads to a wide range of alkyl aryl ketones with good yields. The scope of the developed approach is successfully explored toward the one-step synthesis of 2-arylbenzo[b]furans via sequential addition and intramolecular annulation reactions. The methodology accepted a wide range of substrates and is applicable to library synthesis.
