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]
In organic chemistry, triflate (systematic name: trifluoromethanesulfonate), is a functional group with the formula R−OSO 2 CF 3 and structure R−O−S(=O) 2 −CF 3. The triflate group is often represented by −OTf, as opposed to −Tf, which is the triflyl group, R−SO 2 CF 3. For example, n-butyl triflate can be written as CH 3 CH 2 CH ...

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 the trifluoromethanesulfonate derivative of trimethylsilyl. [1] It is mainly used to activate ketones and aldehydes in organic synthesis.
CF 3 SO 2 OAg + RX → CF 3 SO 2 OR + AgX (X = iodide usually) In coordination chemistry, the salt is also useful to replace halide ligands with the more labile triflate ligand. For example, bromopentacarbonylrhenium can be converted to the more labile derivative using silver triflate: [6] CF 3 SO 2 OAg + BrRe(CO) 5 → CF 3 SO 2 ORe(CO) 5 + AgBr
