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.
Trimethylsilyl azide is the organosilicon compound with the formula (CH 3) 3 SiN 3. A colorless liquid, it is a reagent in organic chemistry, ...
Trimethylsilyl chloride, also known as chlorotrimethylsilane is an organosilicon compound (silyl halide), with the formula (CH 3) 3 SiCl, often abbreviated Me 3 SiCl ...
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.
Trimethylsilyl isothiocyanate (TMSNCS) is an organosilicon compound that contains an isothiocyanate whose nitrogen atom is covalently bonded to a trimethylsilyl group. The isothiocyanate group is an analog of the isocyanate group, but having a sulfur instead of oxygen.
Trimethylsilylacetylene is commercially available. It may also be prepared in a manner similar to other silyl compounds: deprotonation of acetylene with a Grignard reagent, followed by reaction with trimethylsilyl chloride. [4] Trimethylsilylacetylene is a precursor to 1,4-bis(trimethylsilyl)buta-1,3-diyne, a protected form of 1,3-butadiyne. [5]
Tris(trimethylsilyl)methane is the organosilicon compound with the formula (tms) 3 CH (where tms = (CH 3) 3 Si). It is a colorless liquid that is highly soluble in hydrocarbon solvents. It is a colorless liquid that is highly soluble in hydrocarbon solvents.
Lithium, sodium, and potassium bis(trimethylsilyl)amides are commercially available. When free of solvent, the lithium [5] and sodium [6] complexes are trimeric, and ...
