What is the name reaction of conversion of ethyl acetate into acetoacetic ester?

What is the name reaction of conversion of ethyl acetate into acetoacetic ester?

Acetoacetic ester synthesis is a chemical reaction where ethyl acetoacetate is alkylated at the α-carbon to both carbonyl groups and then converted into a ketone, or more specifically an α-substituted acetone. This is very similar to malonic ester synthesis.

Which one is major product after Ketonic hydrolysis of ethyl Aceto acetate?

This type of hydrolysis of ethyl acetoacetate (or its alkyl derivatives) to give a ketone is called ketonic hydrolysis. O= (4) Acid Hydrolysis. When ethyl acetoacetate is hydrolysed with concentrated NaOH and then acidified with dilute HCl, acetic acid is formed.

Is ethyl acetoacetate and acetoacetic ester same?

ethyl acetoacetate (CH3COCH2COOC2H5), also called acetoacetic ester, an ester widely used as an intermediate in the synthesis of many varieties of organic chemical compounds.

How acetoacetic acid is formed?

Acetoacetic Acid Is Formed in the Liver A large share of the degradation of fatty acids into acetyl-CoA occurs in the liver, but the liver uses only a small portion of the acetyl-CoA for its own intrinsic metabolic processes. Instead, pairs of acetyl-CoA condense to form molecules ofacetoacetic acid.

What is the product of decarboxylation of acetoacetic acid?

The decarboxylation of acetoacetic acid, a β-keto acid, occurs by way of a cyclic transition state in which a proton is transferred from the carboxylate atom to the carbonyl oxygen to give an enol that rapidly tautomerizes to give acetone.

What is acetoacetic ester synthesis?

Acetoacetic Ester Synthesis. When α-keto acetic acid is treated with one mole of a base, the methylene group which is more acidic reacts with the base. And the reaction with an alkylation reagent gives alkyl products attached to methylene.

What is ethyl acetoacetate?

Ethyl acetoacetate appears as a colorless liquid with a fruity odor. Flash point 185°F. Boiling point 365°F. May cause adverse health effects if ingested or inhaled. May irritate to skin, eyes and mucous membranes. Used in organic synthesis and in lacquers and paints. Ethyl 3-oxobutanoate is an oxo carboxylic acid.

How can I deprotonate Acetoacetic esters?

For example, alkylation of cyclohexanone requires using LDA, while acetoacetic ester can be deprotonated by sodium ethoxide: Careful, however, not to choose a base solely based on satisfying the pKa requirement!

Why is ethyl acetone more reactive than other esters?

ETHYL ACETOACETATE, a beta-keto ester, is more reactive than many esters. Undergoes an exothermic cleavage reaction in the presence of concentrated base.
