Description

General description

Chlorotrimethylsilane (TMSCl) is a silylating agent employed in the silylation of alcohols, amines, carboxylic acids, thiols, and other functional groups. Silyl group serves as a protecting group for these original functional groups.

Application

Chlorotrimethylsilane (TMSCl) can be used as a reagent:

• To synthesize allenylsilane via carbolithiation of conjugated enynes with aryllithium.
• In the reductive coupling of aldehydes and ketones to produce corresponding 1,2 diols in the presence of zirconocene dichloride and magnesium.
• To prepare 4,4′-bis(trimethylsilyl)bicyclohexyl-2,2′-diene from 1,3-cyclohexadiene by reductive disilylation reaction.
