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 ...
3 anions. Scandium triflate is used as a reagent in organic chemistry as a Lewis acid . [ 1 ] Compared to other Lewis acids, this reagent is stable towards water and can often be used in organic reactions as a true catalyst rather than one used in stoichiometric amounts.
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.
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.
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. [2] [3] It is a hygroscopic, colorless, slightly viscous liquid and is soluble in ...
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.
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).
