In this study, 2‐(benzylamino)naphthalene‐1,4‐dione (4a) was used as the starting material to carry out a one‐pot catalytic reaction in acetic acid with divalent palladium metal Pd(OAc)2 in a nitrogen atmosphere. Two compounds, 5a and 6a, were observed unexpectedly. Both compounds were characterized...
