The CN shuffle: The described intramolecular alkenyl‐ and acylcyanation reaction of activated alkenes proceed by cleavage of a CN bond. This protocol provides access to functionalized acyclic nitriles with quaternary carbon centers under neutral and mild reaction conditions, demonstrates broad scope, and good functional‐group compatibility and versatility.
