A Strain‐Releasing Trap for Highly Reactive Electrophiles: Structural Characterization of Bowl‐Shaped Arenium Carbocations

Abstract

Trap for electrophiles: The reaction of corannulene with halogenated hydrocarbons in the presence of AlCl3 gave the products of an electrophilic attack on the hub carbon atom of the curved aromatic surface (see picture). The X-ray diffraction characterization of a series of bowl-shaped cations illustrates structural deformations caused by the site-directed interior surface functionalization.
