Enolate mechanism. If the catalyst is a moderate base such as hydroxide ion or an alkoxide, the aldol reaction occurs via nucleophilic attack by the resonance-stabilized enolate on the carbonyl group of another molecule. The product is the alkoxide salt of the aldol product. The aldol itself is then formed, and it may then undergo dehydration to give the unsaturated carbonyl compound.

Recent Literature. Catalytic Bu 4 NOAc as silicon activator of ethyl 2-(trimethylsilyl)acetate enables the synthesis of β-hydroxy esters, whereas catalytic Bu 4 NOTMS provides α,β-unsaturated esters. The established reaction conditions were applicable to a diverse range of aromatic, heteroaromatic, aliphatic aldehydes and ketones.

When keto-enol tautomerism occurs the keto or enol is deprotonated and an anion, which is called the enolate, is formed as intermediate.Enolates can exist in quantitative amounts in strictly Brønsted acid free conditions, since they are generally very basic. In enolates the anionic charge is delocalized over the oxygen and the carbon. Enolate forms can be stabilized by this delocalization of.
