Triflic acid is mainly used in research as a catalyst for esterification. It is a hygroscopic, colorless, slightly viscous liquid and is soluble in polar solvents .
Is triflic acid polar or nonpolar?
Triflic acid is a hygroscopic, colorless liquid at room temperature. It is soluble in polar solvents such as dimethylformamide ( DMF ), dimethyl sulfoxide ( DMSO ), acetonitrile, and dimethyl sulfone. Addition of triflic acid to polar solvents can be dangerously exothermic.
What is triflic anhydride?
Triflic anhydride is an organosulfonic anhydride. It derives from a triflic acid. Copyright © 1980, 1981-2021 John Wiley & Sons, Inc.
Is triflic acid a superacid?
It is often regarded as one of the strongest acids, and is one of a number of so-called “superacids”. Triflic acid is widely used especially as a catalyst and a precursor in organic chemistry. With an Ka = 8. 0 1014 (pKa ~ -15) mol/kg, HOTf qualifies as a superacid.
What is the IUPAC name for triflidic acid?
Triflidic acid ( IUPAC name: tris[(trifluoromethyl)sulfonyl]methane, abbreviated formula: Tf3CH) is an organic superacid. It is one of the strongest known carbon acids and is among the strongest Brønsted acids in general, with an acidity exceeded only by the carborane acids.
Does triflic acid sulfonate substrates?
Further recommending its use, triflic acid does not sulfonate substrates, which can be a problem with sulfuric acid, fluorosulfuric acid, and chlorosulfonic acid. Below is a prototypical sulfonation, which HOTf does not undergo: Triflic acid fumes in moist air and forms a stable solid monohydrate, CF 3 SO 3 H·H 2 O, melting point 34 °C.
What is the function of triflic acid derivative catalysts?
These triflic acid derivative catalysts are very effective in isomerizing straight chain or slightly branched hydrocarbons that can increase the octane rating of a particular petroleum-based fuel. Triflic acid reacts exothermically with alcohols to produce ethers and olefins.
