These compounds, which have a Hammett function of 12 or below, were used to elucidate the structure of stable carbocations by George Olah.
Kim and Klein observed extremely long-distance proton jumping in these compounds. Catalysis that proceeds via enzyme-bound metal ions is sometimes named for these compounds, reflecting the metal ion's "electron sink" role. These compounds, which have a Hammett function of 12 or below, were used to elucidate the structure of stable carbocations by George Olah. They are commercially important due to their ability to catalyze hydrocarbon cracking, and antimony pentafluoride was a component of one example which was called "magic" due to its ability to dissolve paraffin. They are typically viscous liquids and derive their name from their ability to donate protons more readily than pure H2SO4. For 10 points, name these conjugate Lewis-Bronsted solutions with extremely low pH.
