Abstract

The hydrolysis reactions of Ti(OⁱPr)₄ in the presence of different ionic liquids using ethanol as solvent were investigated. The reaction in the presence of [BMIM][BF₄] gave rise to the anion exchange reaction product [BMIM]₂[Ti(OH)₆] in moderate yield. On the contrary, Ti₇O₄(OEt)₂₀ was obtained in ionic liquids with other anions. The anion exchange reaction has a broad capacity for group functionalization. It can be used to synthesize both imidazolium and pyridium [Ti(OH)₆]^2- salts. In contrast, under the similar reaction conditions, the reactions of zirconium alcoholate gave rise to [Zr(OH)₅]^- or [Zr(OH)₆] ^2- intermediates depending on the counter cations. Under the solvothermal reaction conditions, [PF₆]^- based ionic liquids can also undertake the similar anion exchange reactions.
