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.
A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry. This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3 ) 3 ], which is in turn bonded to the rest of a molecule.
1-O-Acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose is further reacted with trimethylsilyl trifluoromethanesulfonate (TMSOTf) under the silyl-Hilbert–Johnson reaction and deprotected by an acid or base to form a pure artificial nucleotide.
Trimethylsilyl chloride, also known as chlorotrimethylsilane is an organosilicon compound (silyl halide), ... and trimethylsilyl trifluoromethanesulfonate (TMSOTf).
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).
Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF 3) is an organosilicon compound with the formula CF 3 Si(CH 3) 3.It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group.
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 ...
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]
