Scandium trifluoromethanesulfonate, commonly called scandium triflate, is a chemical compound with formula Sc(SO 3 CF 3) 3, a salt consisting of scandium cations Sc 3+ and triflate SO 3 CF − 3 anions. Scandium triflate is used as a reagent in organic chemistry as a Lewis acid. [1]
For example, n-butyl triflate can be written as CH 3 CH 2 CH 2 CH 2 OTf. The corresponding triflate anion , CF 3 SO − 3 , is an extremely stable polyatomic ion ; this comes from the fact that triflic acid ( CF 3 SO 3 H ) is a superacid ; i.e. it is more acidic than pure sulfuric acid , already one of the strongest acids known.
Lanthanide triflates are proposed for Friedel-Crafts acylations and alkylations, which are often carried out with AlCl 3 as the catalyst in an organic solvent. The nature of the Friedel-Craft reaction, especially the acylation, forces the AlCl 3 to irreversibly complex with any oxygen-containing group in the product, with the only way of decomplexing it being to destroy the AlCl 3 part with ...

Trimethylsilyl trifluoromethanesulfonate (TMSOTf) is an organosilicon compound with the formula (CH 3) 3 SiO 3 SCF 3. It is a colorless moisture-sensitive liquid. It is a colorless moisture-sensitive liquid.
Silver trifluoromethanesulfonate, or silver triflate is the triflate (CF 3 SO 3 −) salt of Ag +. It is a white or colorless solid that is soluble in water and some organic solvents including, benzene. It is a reagent used in the synthesis of organic and inorganic triflates.
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] The compound is closely related to methyl fluorosulfonate (FSO 2 OCH 3).
Zinc trifluoromethanesulfonate or zinc triflate is the zinc salt of trifluoromethanesulfonic acid.It is commonly used as a Lewis acid catalyst, e.g. in silylations. [1]A white powder, zinc triflate is commercially available, though some workers have experienced inconsistent results with zinc triflate from different sources.
