Quality Level 200 DESCRIPTION Application Chlorotrimethylsilane (TMSCl) can be used as: - A reagent to protect alcohol and amine groups via the formation of trimethylsilyl ethers and trimethylsilyl amines.[1][2] - A catalyst for the preparation of 1,3-diphenyl-2-propenone derivatives (chalcones) as antimicrobial agents.[2] - A trapping agent for the anions generated during acyloin condensation reaction.[3] - 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.[4] - A catalyst in the transesterification of triglycerides with alcohols to form fatty acid alkyl esters.[5] - A reagent along with lithium bromide for the conversion of alcohols to the corresponding bromides.[6] - A reagent in Fischer glycosidation.[7] - A source of acid catalyst in the reductive benzylation reaction using benzaldehyde and Et3SiH.[8] - 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.[9] General description Chlorotrimethylsilane is a chloroorganosilane compound mainly used for silylation reactions.[10] |
