haloniumionin
Haloniumionin is a proposed class of polyhalogenated cations in inorganic chemistry, often denoted as [X_n]+, where X is a halogen such as chlorine, bromine, or iodine. The concept encompasses cationic species that can form in non-aqueous media under strong Lewis acidic conditions. Haloniumionin is not a single fixed compound but a family of related ions, studied primarily in theoretical contexts and under laboratory conditions.
Structure and bonding: In haloniumionin species, halogen atoms populate a cationic core with hypervalent bonding. Geometries
Synthesis and stabilization: Haloniumionins are accessed by oxidation of dihalogen precursors in the presence of strong
Reactivity and potential applications: As highly electrophilic species, haloniumionins can add to alkenes to form halonium
Safety and status: Haloniumionins are not standard laboratory reagents. They can release reactive halogen species and
