一般描述
Reaction of ethyl trimethylsilylacetate (ETSA) with dilute hydrochloric acid, dilute alkali, anhydrous HCl, anhydrous bromine and absolute ethanol has been reported. ETSA undergoes condensation with aromatic aldehydes in the presence of base catalyst to yield β-trimethylsiloxycarboxylates. Lithium ETSA reacts with ketones to yield α,β-unsaturated esters.
应用
Ethyl trimethylsilylacetate (ETSA) was used in the synthesis of ethyl-2,2-dibromo-2-(trimethylsilyl)acetate. It was also used to silylate the enolizable aldehydes and ketones
