Cover Feature: Increasing the Lewis Acidity of Pyramidal Boranes: Cationic 9‐Bora‐1‐Azatriptycenes as Strong Boron Lewis Superacids (ChemistryEurope 5/2025)
The Cover Feature illustrates the discovery of new dimensions of Lewis acidity in boron chemistry. In their Research Article (DOI: 10.1002/ceur.202500100), G. Berionni and co-workers explain how they developed new pyramidal boron Lewis superacids containing a pyridine/pyridinium unit ready to be switched in Lewis acidity and charge. New coordination modes between boron and weakly coordinating anions are observed and several boron and nitrogen containing anthracene, triptycene and bis-triptycene motifs, which are represented on the image, have been isolated.
