| Application: | Possible usages of chlorotrimethylsilane: • Chloromethylation of polysulfones (PSUs). • Activation of lithium hydride to convert it into a hydride source for the reductive silylation of carbonyl compounds. • Chlorotrimethylsilane/l • Chlorotrimethylsilane is a non-toxic alternative to mercuric chloride in activating in samarium-promoted cyclopropanation of both allylic and α-allenic alcohols. It is also used in Fisher glycosylation. |
| General description: | Chlorotrimethylsilane is a chloro-organosilane compound mainly used for silylation reactions. |
