Taming the highly reactive oxonium ion.
'Onium rings: Incorporation of the trivalent oxygen atom as a structural element within the tricyclic core of 1-3 imparts unprecedented stability to this "extraordinary" class of tertiary oxonium ions. Cation 1 is the least reactive and can be refluxed in water for 72 hours with no noticeable decomposition.
