Popis: | A new kind of ionic liquid (IL) with strong Brønsted acidity, i.e., a hydronium (H₃O⁺) solvate ionic liquid, is reported. The IL can be described as [H₃O⁺·18C6]Tf₂N, where water exists as the H₃O⁺ ion solvated by 18-crown-6-ether (18C6), of which the counter anion is bis(trifluoromethylsulfonyl)amide (Tf₂N⁻; Tf = CF₃SO₂). The hydrophobic Tf₂N⁻ anion makes [H₃O⁺·18C6]Tf₂N, evaluated using the indicator method, is a new record for ILs and indicates strong aciditiy. The findings regarding this proton-condensed solvate IL are of fundamental interest, and will help in the design of media for new acid-base reactions. This was Paper 3475 presented at the Honolulu, Hawaii, Meeting of the Society, October 2–7, 2016. |
