Definitions
- the invention relates to halogenated tetrasilylboranates, processes for their production and their use.
- Tetrasilylboranates are already known. For example, refer to the publication by Nöth et al. in Chem. Ber. 1982, 115, 934, in which the synthesis of Li + B (SiCH 3 ) 4 - is described by reacting trimethoxyborane with trimethylsilyllithium under organometallic conditions.
- halogenated tetrasilylboranates are also weakly coordinating and stabilizing anions for organic cations, which are of great industrial importance as catalysts.
- Halogenated tetrasilylboranates are technically important, especially with the cation Ph 3 C + , since they can easily be converted into catalytically active compounds; they are technically important catalyst precursors.
- Protonic acid compounds are compounds that are able to donate protons. The weaker the proton is bound to the anion in the protonic acid compound, the easier it can be transferred to a substrate and the greater its acidity. Tetrafluoroboric acid (H + BF 4 -), perchloric acid (H + C10 4 -), trifluoromethanesulfonic acid (CF 3 SO 3 H) and hexafluoroantimonic acid (H + SbF6 ⁇ ) therefore have high acid strengths. These acids are also known as super acids because they have a very high acid strength. However, disadvantages of these acids are that they are difficult to prepare, difficult to handle because of their high corrosiveness and their decomposability.
- Tetrafluoroboric acid is only stable in water or water-like solvents and can only be produced in solution. This also applies to perchloric acid. If the water content is reduced, there is a risk of explosions with perchloric acid; in addition, perchloric acid has an oxidizing effect, which is a further disadvantage.
- Trifluoromethanesulfonic acid is produced by the electrochemical fluorination of methanesulfonic acid chloride, hexafluoroantimonic acid by the reaction of anhydrous hydrogen fluoride with SbF 5 . These procedures can only be carried out in special systems. These properties of the known very strong acids therefore make their technical use considerably more difficult.
