Triflic acid, the short name for trifluoromethanesulfonic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF 3 SO 3 H. It is one of the strongest known acids . Triflic acid is mainly used in research as a catalyst for esterification .
Triflate salts are thermally very stable with melting points up to 350 °C for sodium, boron and silver salts especially in water-free form. They can be obtained directly from triflic acid and the metal hydroxide or metal carbonate in water.
The simplest example of a perfluorosulfonic acid is the trifluoromethanesulfonic acid. Perfluorosulfonic acids with six or more perfluorinated carbon atoms, i.e. from perfluorohexanesulfonic acid onwards, are referred to as long-chain. [1] Perfluorooctanesulfonic acid Trifluoromethanesulfonic acid
Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula (CF 3 SO 2) 2 O. It is the acid anhydride derived from triflic acid . This compound is a strong electrophile , useful for introducing the triflyl group , CF 3 SO 2 .
Commercially available superacids include trifluoromethanesulfonic acid (CF 3 SO 3 H), also known as triflic acid, and fluorosulfuric acid (HSO 3 F), both of which are about a thousand times stronger (i.e. have more negative H 0 values) than sulfuric acid.
Methyl trifluoromethanesulfonate, also commonly called methyl triflate and abbreviated MeOTf, is the organic compound with the formula CF 3 SO 2 OCH 3.It is a colourless liquid which finds use in organic chemistry as a powerful methylating agent. [2]
Triflidic acid (IUPAC name: tris[(trifluoromethyl)sulfonyl]methane, abbreviated formula: Tf 3 CH) 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 .
Copper(II) triflate is the copper(II) salt of trifluoromethanesulfonic acid (known simply as triflic acid) which has a chemical formula of Cu(OSO 2 CF 3) 2, abbreviated Cu(OTf) 2. This substance, first reported in 1972, [2] is a powerful Lewis acid.
