Substituent matters: A skeleton rearrangement of 1‐aryl‐3‐benzazepines was developed with 2.0 equiv of FeCl3⋅6 H2O in PhNO2. The N‐substituents had a dramatic influence on the structures of the products. In the case of N‐alkylbenzazepines, 1‐aryltetrahydroisoquinolines were obtained, whereas N‐acyl‐benzazepines yielded a series of unique C1 quaternary 1‐aryl‐1‐formyltetrahydroisoquinolines.
