Organic chlorosilanes are frequently used as coatings for silicon and glass surfaces, and in the production of silicone (polysiloxane) polymers. While phenyl chlorosilanes and many others can be used, methylsiloxanes are produced in the greatest quantities. [citation needed] Methyl chlorosilanes have one to three methyl groups.
A combination of methyltrichlorosilane and sodium iodide can be used to cleave carbon-oxygen bonds such as methyl ethers. R'OR + MeSiCl 3 + NaI + H 2 O → R'OH + RI + MeSiCl 2 (OH) + NaCl. Esters and lactones can also be cleaved with methyltrichlorosilane and sodium iodide to give the corresponding carboxylic acids. Acetals convert to carbonyl ...
It is commonly abbreviated as TBSCl or TBDMSCl. It is a chlorosilane containing two methyl groups and a tert-butyl group. As such it is more bulky that trimethylsilyl chloride. It is a colorless or white solid that is soluble in many organic solvents but reacts with water and alcohols. The compound is used to protect alcohols in organic ...
TMSCl is reactive toward nucleophiles, resulting in the replacement of the chloride. In a characteristic reaction of TMSCl, the nucleophile is water, resulting in hydrolysis to give the hexamethyldisiloxane: + + The related reaction of trimethylsilyl chloride with alcohols can be exploited to produce anhydrous solutions of hydrochloric acid in alcohols, which find use in the mild synthesis of ...
Although proportionately a minor outlet, organosilicon compounds are widely used in organic synthesis. Notably trimethylsilyl chloride Me 3 SiCl is the main silylating agent. One classic method called the Flood reaction for the synthesis of this compound class is by heating hexaalkyldisiloxanes R 3 SiOSiR 3 with concentrated sulfuric acid and a ...
The mechanism of the direct synthesis is not known. However, the copper catalyst is essential for the reaction to proceed. In addition to dimethyldichlorosilane, products of this reaction include CH 3 SiCl 3 , CH 3 SiHCl 2 , and (CH 3 ) 3 SiCl , which are separated from each other by fractional distillation .
TMS is a by-product of the production of methyl chlorosilanes, SiCl x (CH 3) 4−x, via the direct process of reacting methyl chloride with silicon. The more useful products of this reaction are those for x = 1 (trimethylsilyl chloride), 2 (dimethyldichlorosilane), and 3 (methyltrichlorosilane).
