A copper-hydride-catalyzed silylative dehydration of primary amides is an economical approach to the synthesis of nitriles. The reaction avoids a typically challenging 1,2-siloxane elimination step, proceeds at ambient temperature, and tolerates a variety of metal-, acid-, or base-sensitive functional groups.
