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.
Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH 3 CH 2 CH 2 COOCH 2 CH 3. It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple, and is a key ingredient used as a flavor enhancer in processed orange juices. [1]

A less expensive alternative reagent is 2-methylbut-3-yn-2-ol, which after alkynylation is deprotected with base. 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 .
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
The molecular formula C 8 H 14 O 4 may refer to: Diethyl succinate; Dimethyl_adipate; Ethyl acetoxy butanoate; Fructone; Suberic acid; 2,2,3,3-Tetramethylsuccinic acid
Hexamethyldisiloxane can be produced by the addition of trimethylsilyl chloride to purified water: 2 Me 3 SiCl + H 2 O → 2 HCl + O[Si(CH 3) 3] 2. It also results from the hydrolysis of silyl ethers and other silyl-protected functional groups. HMDSO can be converted back to the chloride by reaction with Me 2 SiCl 2. [3]
