Difluorboryl‐Komplexe von Di‐ und Tripyrrylmethenen
Abstract
Di‐ und Tripyrrylmethene bilden mit Bortrifluorid in Gegenwart von tert. Basen stabile, gelbe bis rote Difluorboryl‐Komplexe 1–9, die bei Anwesenheit negativer Substituenten Alkalisalze (z. B. 12–14) bilden können. Alle Dipyrrylmethen/Bor‐Komplexe sind durch intensive Fluoreszenz ausgezeichnet. Ebenso wie die Salzbildung ist der Verlauf der katalytischen Hydrierung (3 → 16, 7 → 17) von der Substitution der Pyrrol‐Kerne abhängig. – Auch Aluminium bildet stark fluoreszierende Komplexe mit Dipyrrylmethenen, die aber wegen ihrer extremen Wasserempfindlichkeit noch nicht näher untersucht wurden. – Das Tripyrrylmethen 11 wurde durch Reaktion eines Pyrrol‐Derivates mit Oxalylchlorid erhalten.

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.
