Abstract

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. More information can be found in the Research Article by A. Amonov and S. Scheiner (DOI: 10.1002/cphc.202400482).

封面专题：多环芳烃π系统的卤素键合（ChemPhysChem 18/2024）

卤素原子（X）（如 Br 或 I）取代 H 键的桥氢会形成 CX⋅⋅B 卤素键。大多数此类卤素键都从 B 亲核体的孤对电子中提取电子密度。不过，苯等芳香系统或其较大的多环系统（如萘、蒽和冠烯）的扩展 π 电子云也可在此类卤素键中充当亲核体，其键强度可与传统的卤素键和氢键相媲美。更多信息，请参阅 A. Amonov 和 S. Scheiner 的研究文章（DOI: 10.1002/cphc.202400482）。
