Categories : Superacids. Fluoroantimonic acid is used in chemical engineering and organic chemistry to protonate organic compounds, regardless of their solvent. Encyclopedia of Reagents for Organic Synthesis. The following values show that fluoroantimonic acid is much stronger than other superacids [4] based upon the Hammett acidity function. Diborolyl-metal complexes featuring MC 3 B 2 and M 2 C 3 B 2 cages, representing another type of metallacarborane, have also been extensively studied [16]. Geometrical isomers of carboranes can exist, necessitating the use of the numerical prefixes in a compound's name; this is illustrated by the 1,2- 1,7- and 1,2-C 2 B 10 H 12 icosahedral clusters referred to earlier.

  • What Is the World's Strongest Superacid

  • Carborane acids H(CXB11Y5Z6) (X, Y, Z = H, Alk, F, Cl, Br, CF3) are a class of superacids, some of which are estimated to be at least one million times stronger.

    Carboranes are electron-delocalized (non-classically bonded) clusters composed of boron, The icosahedral CB11H12− anion is a strong acid, and its polychlorinated derivative H(CHB11Cl11) is a superacid. The icosahedral charge -neutral.

    Fluoroantimonic acid is an inorganic compound with the chemical formula H 2 FSbF 6 It is an Only the carborane acids, whose H0 could not be directly determined due to their high melting points, may be stronger acids than fluoroantimonic.
    Many dicarbaboranes exist as isomers that differ in the relative location of the carbon centers. Wilkinson, C.

    Mono carboranes are clusters with B n C cages.

    OsF 4 OsF 5. Fluoroantimonic acid is a mixture of hydrofluoric acid and antimony pentafluoride. PtF 4. It is only used in a solution of hydrofluoric acid.

    According to the classical definition, a superacid is an acid with an acidity greater than that of of this kind is fluoroantimonic acid.

    Another group of superacids, the carborane acid group, contains some of the strongest known acids. The compound, called a carborane acid, is the first 'superacid' that can be stored in a bottle, say its creators. The previous record-holder.
