产品描述

General description

Chlorotrimethylsilane is a chloroorganosilane compound mainly used for silylation reactions.[1]

Application

Chlorotrimethylsilane (TMSCl) can be used as:       
•  A reagent to protect alcohol and amine groups via the formation of trimethylsilyl ethers and trimethylsilyl amines.[4][5]      
•  A catalyst for the preparation of 1,3-diphenyl-2-propenone derivatives (chalcones) as antimicrobial agents.[5]        
•  A trapping agent for the anions generated during acyloin condensation reaction.[6]       
•  A better alternative catalyst to the toxic mercuric chloride for the activation of samarium (Sm) during the cyclopropanation of both allylic and α-allenic alcohols.[7]
•  A catalyst in the transesterification of triglycerides with alcohols to form fatty acid alkyl esters.[8]        
•  A reagent along with lithium bromide for the conversion of alcohols to the corresponding bromides.[9]       
•  A reagent in Fischer glycosidation.[10]       
•  A source of acid catalyst in the reductive benzylation reaction using benzaldehyde and Et3SiH.
• A reagent to synthesize sodium trimethylsilanethiolate (Me3SiSNa) by reacting with sodium sulfide, which is an odorless alternative method of synthesizing Me3SiSNa from foul-smelling bis(trimethylsilyl)sulfide and sodium methoxide.[2]
