Tetra‐p‐tolylporphyrin with an Inverted Pyrrole Ring: A Novel Isomer of Porphyrin
Abstract
Exchange of a β-methine unit for an N atom of a pyrrole ring of a porphyrin leads to a new type of porphyrin isomer, which is formed by condensation of pyrrole and P-tolylaldehyde. NiII ions are surprisingly coordinated by 1 as tetradentate ligand, that is through the three N atoms and the C atom of the inner cycle. The framework of the green metalloporhyrin is planar.

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.
