Aromaticity and Antiaromaticity in Five‐Membered C4H4X Ring Systems: “Classical” and “Magnetic” Concepts May Not Be “Orthogonal”
Abstract
Energetic, geometric, and magnetic criteria yield quantitatively the same order of aromaticity (antiaromaticity) for the five-membered ring systems 1: the aromatic 6π electron systems are stabilized, their bond lengths are equalized, and the magnetic susceptibility exaltations are diamagnetic. In contrast, the antiaromatic 4π electron systems are destabilized, double bonds are localized, and susceptibility exaltations are paramagnetic.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
