A halonium ion is any onium ion containing a halogen atom carrying a positive charge. This cation has the general structure R− −R′ where X is any halogen and no restrictions on R, this structure can be cyclic or an open chain molecular structure. Halonium ions formed from fluorine, chlorine, bromine, and iodine … See more The simplest halonium ions are of the structure H− −H (X = F, Cl, Br, I). Many halonium ions have a three-atom cyclic structure, similar to that of an epoxide, resulting from the formal addition of a halogenium ion X … See more These ions are usually only short-lived reaction intermediates; they are very reactive, owing to high ring strain in the three-membered ring and the positive charge on the … See more Halonium ions were first postulated in 1937 by Roberts and Kimball to account for observed anti diastereoselectivity in halogen addition reactions to alkenes. They correctly argued that if the initial reaction intermediate in bromination is the open-chain X–C–C … See more WebDefinition of halonium in the Definitions.net dictionary. Meaning of halonium.
