Abstract
A straightforward and convenient preparation of 25 novel imidazolium salts from the corresponding 1H-isochromeno[3,4-d]imidazolones is described, employing either a quaternization or a quaternization/anion metathesis strategy. The nature of the anion has a major influence on the melting point of these imidazolium salts (BF4 > I, PF6 > N(Tf)(2), N(CN)(2) > OTf).
