Transition states. Optimized structures and relative Gibbs free energies (in kcal/mol) of the transition states of the aminative dearomatization step (ωB97XD/def2-TZVPP//B97D/6-31G**). The catalysts are presented with the van der Waals model. The substrates are presented with the stick model. The forming C–C bonds are shown in yellow dash lines. The transferring protons are shown in green spheres. The intact benzene rings of α-naphthols are shown in pink
