Bis(trifluoromethanesulfonyl)aniline is the organic compound with the formula C 6 H 5 N(SO 2 CF 3) 2. [1] It is a white solid. The compound is used to install the triflyl group (SO 2 CF 3). Its behavior is akin to that of triflic anhydride, but milder.
Triflyl group. In organic chemistry, the triflyl group (systematic name: trifluoromethanesulfonyl group) is a functional group with the formula R−SO 2 CF 3 and structure R−S(=O) 2 −CF 3.
Bistriflimidic acid. The conjugate acid of bistriflimide, which is frequently referred to by the trivial name bistriflimidic acid (CAS: 82113-65-3), is a commercially available superacid.
Preparation of the trifluoromethyltrimethylsilane was reported by Ingo Ruppert in 1984. [11] In 1989, Prakash and Olah first reported activation of TMSCF 3 by fluoride to perform nucleophilic trifluoromethylation of carbonyl compounds. [12]

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.
In the laboratory, triflic acid is useful in protonations because the conjugate base of triflic acid is nonnucleophilic. It is also used as an acidic titrant in nonaqueous acid-base titration because it behaves as a strong acid in many solvents (acetonitrile, acetic acid, etc.) where common mineral acids (such as HCl or H 2 SO 4) are only moderately strong.
Sodium trifluoromethanesulfinate (CF 3 SO 2 Na) is the sodium salt of trifluoromethanesulfinic acid. Together with t-butyl hydroperoxide, an oxidant, this compound was found to be a suitable reagent for introducing trifluoromethyl groups onto electron-rich aromatic compounds by Langlois; this reagent is also known as the Langlois reagent.
