Structurally diverse aromatic and aliphatic ionic liquids have been prepared via anion
metathesis utilizing alkylammonium chlorides and trimethyl phosphate. Excellent oxygen-containing
functional-group tolerance in preparation of potentially greener dimethyl phosphate
ionic liquids has been demonstrated. For the first time, this method has been employed
in the synthesis of dicationic imidazolium-based ionic liquids possessing a dimethyl
phosphate counterion, providing a simple, direct route towards structurally novel
products of high purity.
