Zur Existenz niedergliedriger Cycloalkine, I
Abstract
Während wie bereits bekannt – Cyclononin und Cyclooctin isolierbare Kohlenwasserstoffe sind, ließen sich trotz vielfacher Bemühungen anderer Autoren die niederhomologen Cycloalkine nicht in substantia fassen. Eigene Versuche an Bishydrazonen der zugehörigen Cycloalkan‐dione, die mit Quecksilberoxyd behandelt wurden, bestätigten das. — Daß diese Cycloalkine kurzlebig auftreten, konnte bei Wiederholung der Oxydationsreaktionen in Gegenwart von 2.5‐Diphenyl‐3.4‐benzofuran sowie Phenylazid festgestellt werden. Die zu erwartenden Addukte wurden isoliert und in ihrer Struktur aufgeklärt. Die sinkenden Ausbeuten an Abfangprodukten legen den Schluß nahe, daß die Stabilitäten des Cycloheptins, Cyclohexins und Cyclopentins infolge der mit fallender Ringgröße wachsenden Spannung abnehmen.

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.
