Domino cross-coupling/cyclizationreactions of N-propargyl sulfoximines and 2-iodophenols or 2-iodoanilides are catalyzed by a cooperative palladium/copper system to provide benzo[b]furan and indole derivatives in good to excellent yields. The reactions occur under mild conditions and tolerate a wide variety of functional groups.
