Q.why n(ch3)3 is pyramidal but n(sih3)3 is planar while both

TMS Iodide acts in the same way as Lewis acids do. The capacity of the latent phenoxide to leave improves as it is coordinated to the ether oxygen. An SN2 reaction then cleaves the ether, yielding alkyl halide and the silylate. The required phenol, acid, and trimethylsiloxide are produced during hydrolysis, resulting in TMS2O.
TMSI is commonly used to produce phenols from aryl alkyl ethers, but it can also be used to cleave dialkyl ethers and deprotect t-Butyl esters. Because of the reagent’s high cost and volatility, it is often made in situ from TMSCl and NaI.

Trimethylsilyl chloride

Using the reaction of 2-methoxybenzaldehydes (as O-methyl protected salicylaldehydes), indoles, and -dicarbonyl compounds, trimethylsilyl iodide (TMSI) is introduced as an effective reagent for the one-pot synthesis of 9-(1H-indol-3-yl)xanthen-4-(9H)-ones. To produce the target product, a series of TMSI reactions involving silylation, silyl enol ether formation, methyl deprotection, and nucleophilic substitution/cyclization are used. The deprotection of the methoxy group by TMSI is the most important step in this procedure.

Class 13 9 protecting alcohols

Iodotrimethylsilane has a high oxygenophilicity against ethers, esters, lactones, acetals, and other molecules with an oxygen atom as a functional group.
In organic synthesis, iodotrimethylsilane is used to introduce the trimethylsilyl group. It can also be used in gas chromatography analysis because it converts alcohol to a silyl ether derivative, which makes it more volatile than the original molecule.
Trimethylsilyliodide is a common blocking agent in pharmaceutical production, and it’s commonly used in drug syntheses. It acts as a silane blocking agent and can selectively protect or deprotect functional groups.
Iodotrimethylsilane is a versatile reagent that can be used in a variety of organic reactions. It’s a dealkylating agent for lactones, ethers, acetals, and carbamates, as well as a trimethylsilylating agent for silyl imino esters, alkyl and alkenyl silanes, and other compounds. In several organic reactions, it also serves as a Lewis acid catalyst and a reducing agent.
