One aspect of the present invention relates to "boronium" ions that are stable, hydrophobic, room-temperature ionic liquids. In certain embodiments, ionic liquids of the instant invention are represented by the formula [X<SUB>n</SUB>BY<SUB>4-n</SUB>]<SUP>+(n-1) </SUP>(n-l)Z<SUP>-1</SUP>, wherein X refers to a Lewis base, Y refers to a substituent covalently bonded to boron, Z<SUP>-1</SUP> is a charge diffuse anion, and x is 2, 3 or 4. In certain embodiments, the ionic liquids of the instant invention are of the general type [X<SUB>2</SUB>BY<SUB>2</SUB>]<SUP>+1</SUP> Tf<SUB>2</SUB>N<SUP>-1</SUP>, wherein each X is independently a tertiary amine, a N-alkylimidazole or a pyridine; and each B-X bond is a B-N bond. |
