palladium-catalyzed method for cross-coupling unactivated secondaryalkyl halides has been a long-standing challenge in synthetic chemistry. This communication describes a simple catalyst system-Ni(cod)2/s-Bu-Pybox-that achieves room-temperature Negishi reactions of an array of functionalized primary and secondaryalkylbromides and iodides.
