magic acid

The name came after a candle was placed in a sample of magic acid.

It was determined that the mechanism depends on the amount of magic acid used.

As use of the Magic acid system became more widespread, however, higher-coordinate carbocations were observed.

Magic acid has low nucleophilicity, allowing for increased stability of carbocations in solution.

George Andrew Olah prepared the so-called magic acid.

One controversial cation, the norbornyl cation, has been observed in several media, Magic acid among them.

Magic acid is capable of protonating alkanes.

Examples of superacids are fluoroantimonic acid, magic acid and perchloric acid.

Magic acid catalyzes cleavage-rearrangement reactions of tertiary hydroperoxides and tertiary alcohols.

The Magic Acid system was developed in the 1960s by George Olah, and was to be used to study stable carbocations.

Magic acid also catalyzes electrophilic hydroxylation of aromatic compounds with hydrogen peroxide, resulting in high-yield preparation of monohydroxylated products.

Predictably, magic acid is highly toxic upon ingestion and inhalation, causes severe skin and eye burns, and is toxic to aquatic life.

In 1962, Olah directly observed the tert-butyl carbocation by nuclear magnetic resonance as a stable species on dissolving tert-butyl fluoride in magic acid.

Mixing antimony pentafluoride (SbF) and fluorosulfonic acid (FSOH) makes magic acid.

The combination of HSOF and the Lewis acid antimony pentafluoride produces "Magic acid," which is a far stronger protonating agent.

Larger alkanes, such as ethane, are also reactive in magic acid, and both exchange hydrogen atoms and condense to form larger carbocations, such as protonated neopentane.

Magic Acid and other superacids are also used to catalyze isomerization of saturated hydrocarbons, and have been shown to protonate even weak bases, including methane, xenon, halogens, and molecular hydrogen.

Near molar equivalency, only O-O cleavage is observed, but with increasing excess of magic acid, C-O cleavage competes with O-O cleavage.

George A. Olah prepared the so-called magic acid, so-named for its ability to attack hydrocarbons, by mixing antimony pentafluoride (SbF) and fluorosulfonic acid (FSOH).

In 1967 the group of George A. Olah obtained NMR spectra of tetramethylethylenebromonium ions by dissolving 2,3-dibromo-2,3-dimethylbutane in magic acid at 60 C. The spectrum for the corresponding fluorine compound on the other hand was consistent with a rapidly equilibrating pair of β-fluorocarbocations.
