General description

Chlorotrimethylsilane is a chloro-organosilane compound mainly used for silylation reactions.

Application

Chlorotrimethylsilane has been used to silanize glass surface to make them more hydrophobic. It can be used in combination with hexamethyldisilazane for the protection of alcohols by forming trimethylsilyl ethers via silylation reaction. Also used in Fisher Glycosylation

Magic-sized clusters (MSCs) can be isolated as intermediates in quantum dot (QD) synthesis, and they provide pivotal clues in understanding QD growth mechanisms. We report syntheses for two families of heterogeneous-atom-incorporated InP MSCs that have chlorine or zinc atoms. All
