We describe a nickel‐catalyzed cyanation reaction of aryl (pseudo)halides that employs butyronitrile as a cyanating reagent instead of highly toxic cyanide salts. A dual catalytic cycle merging retro‐hydrocyanation and cross‐coupling enables the conversion of a broad array of arylchlorides and aryl/vinyl triflates into their corresponding nitriles. This new reaction provides a strategically distinct
