A palladium-catalyzed double isocyanide insertion and elimination enables an efficient one-pot synthesis of α-iminonitriles from readily available aryl halides without using hypertoxic cyanides and excess oxidants. Furthermore, the utility of this reaction was demonstrated by a rapid total synthesis of a quinoxaline.
