Die dynamische Interkonversion …… großer kovalenter organischer Käfige gelang durch Erwärmen oder Behandlung mit Säure/Base. In der Zuschrift auf S. 3167 zeigen N. Iwasawa et al., dass eine Mischung aus den Boroxin‐Käfigverbindungen 12‐mer und 15‐mer mit Pyridin sauber in ein Pyridin‐Addukt des Boroxin‐Käfigs 9‐mer überführt werden kann. Dabei ändert sich die Geometrie der N‐koordinierten Boratome...
Dynamic interconversion between large covalent organic cages was achieved simply by heating or acid/base treatment. A mixture of the boroxine cages 12‐mer and 15‐mer was cleanly converted into a pyridine adduct of the 9‐mer boroxine cage upon treatment with pyridine, and the geometry of N‐coordinated boron atoms changed from trigonal to tetrahedral. The reverse reaction was achieved by heating or...
