Expecting the unexpected: The title reaction leads to satisfactory yields of dihydrodibenzoazepines 1 a from norbornene. The dibenzoazepines 2 can also be accessed from compounds of type 1 b when norbornadiene is used as a reactant. Theoretical studies show that the reaction represents a chelation‐driven deviation from the usual selectivity observed in the presence of ortho‐substituents on the aryl
