Cover Feature: Halogen Bonding to the π‐Systems of Polycyclic Aromatics (ChemPhysChem 18/2024)

Replacement of the bridging hydrogen of the H-bond by a halogen atom (X) such as Br or I leads to a CX⋅⋅⋅B halogen bond. Most such halogen bonds extract electron density from a lone pair of the B nucleophile. However, the extended π-electron cloud of an aromatic system like benzene or its larger polycyclic cousins such as naphthalene, anthracene, and coronene can also act as the nucleophile in such halogen bonds, with bond strengths that rival traditional halogen and hydrogen bonds.
