Charge-tagged N-heterocyclic carbenes

Abstract

The interception, formation and characterization of the first stable, long lived charge-tagged N-heterocyclic carbenes of the general type 4x+ (x = 1–3) and analogues is reported. Via ESI(+)-MS of solutions of bromine salts of doubly, triply and quadruply charged imidazolium ion IL (3.Brn, n = 2–4), the isolated 4x+ as well as charged aggregates [3.Br(nx)]x+ likely to be participating in the [3.Br(nx)]x+4x+ + HBr solution equilibrium could be transferred and characterized in the gas phase. Mimicking the solution equilibrium, the gaseous [3.Br(nx)]x+ were found to dissociate nearly exclusively viaHBr loss during thermal activationvia collisions to form gaseous 4x+, which were found to add to acrolein and acetone.
