What is the product of this aldol condensation reaction?
An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), followed by dehydration to give a conjugated enone.
What is the aldol condensation product from the self reaction of acetone?
Aldol Condensation of Acetone: In the presence of an appropriate base, acetone can undergo self-aldol condensation to an alpha-beta unsaturated ketone. The base will react with acetone to generate an enolate which will react with another molecule of acetone to accomplish the self-aldol condensation.
Which product is major in aldol condensation?
Enolizable aldehydes and enolizable ketones, in the presence of an acid or base catalyst usually in aqueous medium at low temperature, undergo a reaction, giving an aldol as the major product. This reaction is known as aldol reaction.
What is double aldol condensation?
You will do a double mixed-aldol condensation reaction between acetone and benzaldehyde. Acetone has α-hydrogens (on both sides) and thus can be deprotonated to give a nucleophilic enolate anion. The aldehyde carbonyl is much more electrophilic than that of a ketone, and therefore reacts rapidly with the enolate.
What is a self condensation reaction?
Self condensation: A condensation reaction in which two of the same molecule are condensed. This aldol condensation is a self condensation reaction because two molecules of acetone combine to form the product.
Which is formed in the aldol condensation reaction?
Upon reaction with a second carbonyl compound, the β-hydroxy carbonyl compound is formed, which can undergo E1cB elimination of water to form anE-alkene. Scheme 1. Base-catalyzed aldol condensation reaction. Objectives
Why does acetone form an enolate anion with aldehyde?
acetone can form an enolate anion, and it will preferentially react with the more reactive carbonyl group of the aldehyde, ensuring that we only get a single product. Acetone contains enolizable sites on both sides of the carbonyl group and thus a second condensation can occur with a second equivalent of benzaldehyde.
