Hydroarylation of N ‐Allenyl Derivatives Catalyzed by Copper**

A simple copper catalytic system was used to perform the addition of (hetero)aryl nucleophiles to N-allenyl derivatives. This intermolecular C-C bond formation occurs with both complete regio- and stereoselectivity to afford the linear (E) allylic product with moderate to excellent yields. This atom economical method is the first example of hydroarylation of allenes catalyzed by copper.
