Magnetic shielding studies demonstrate that successive hydrogenation of NiII norcorrole (NiNc), a stable molecule combining aromatic and antiaromatic features, first weakens and then eliminates the central antiaromatic region, even though the NiNc antiaromatic “core”, a 14‐membered conjugated cycle with 16 π electrons, is formally preserved throughout the H2NiNc−H8NiNc series. The differences between aromatic and non‐aromatic isotropic shielding distributions and nucleus‐independent chemical shift (NICS) values in these hydrogenated porphyrin analogues are highlighted by comparing the results for the members of the H2NiNc−H8NiNc series to those for the aromatic NiII porphyrin complex. The results strongly support the unexpected and counterintuitive conclusion that H8NiNc will be nonaromatic, without even a trace of antiaromaticity. Based on these findings, H8NiNc is predicted to be the most stable member of the H2NiNc−H8NiNc series.
