Description

General description

Acetyltrimethylsilane is an organosilicon compound that is commonly used as a protective agent for alcohols and amines in organic synthesis. It is also used as a reagent in various reactions, which includes trimethylsilylation, condensation, carbon-carbon bond formation, and reductive amination reactions.

Application

Acetyltrimethylsilane can be used as a reagent in the synthesis of dihydrophenanthrenes via a C-C insertion reaction. It is also used as a source of carbanion in the synthesis of unsymmetrical biaryls by carbanion-induced ring transformation of 2H-pyran-2-ones under mild basic conditions.
