The first thiazolium gold(III) compound that qualifies as an ionic liquid has been prepared and crystallographically characterized. Hydration of phenylacetylene with this compound as catalyst precursor in ionic liquids indicates that gold(Ill)based ionic liquids could serve both as solvents and catalysts for organic transformations. The potential re-use of catalysts is an advantage achieved by recycling the ionic liquid phase. Various imidazolium-derived ionic liquids as well as the new thiazolium compound can be converted into gold carbene complexes by sequential deprotonation and coordination, opening the way for in situ catalyst tailoring.
