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]
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 ...
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 ...

Hf(OTf) 4 mediated synthesis of altertoxins. Hf(OTf) 4, alongside Sc(OTf) 3 and In(OTf) 3, has been shown to activate alkynes and enable electrophilic substitution. In 2004 Song and Lee et al. reported Hf(OTf) 4-catalyzed Friedel-Crafts alkenylation of benzene with alkenyl derivatives. [7] Hf(OTf) 4 enabled electrophilic substitution of alkynes
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.
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.
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
