A novel and facile synthetic protocol for the construction of benzazepine and benzoxepine derivatives through a copper(I)‐catalyzed reaction of 2‐(2‐ethynylphenyl)‐1‐tosylaziridine or 2‐(2‐ethynylphenyl)oxirane with sulfonyl azides is disclosed. A ketenimine is the key intermediate during the reaction process.
