What is the product of acyloin reaction?

Acyloin condensation is a reductive coupling of two carboxylic esters using metallic sodium to yield an α-hydroxyketone, also known as an acyloin. The reaction is most successful when R is aliphatic and saturated….

Which solvent used in acyloin condensation?

The most common method used to make acyloin is the reductive condensation of aliphatic esters with sodium in inert solvents, such as ether, xylene or even in liquid NH3. Trimethylchlorosilane has been reported to improve the yield of this reaction.

How is Pinacol formed?

A pinacol coupling reaction is an organic reaction in which a carbon–carbon bond is formed between the carbonyl groups of an aldehyde or a ketone in presence of an electron donor in a free radical process. The reaction product is a vicinal diol.

How is acetoacetic ester prepared?

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.

Why is it called pinacol?

The name of the rearrangement reaction comes from the rearrangement of pinacol to pinacolone. This reaction was first described by Wilhelm Rudolph Fittig in 1860 of the famed Fittig reaction involving coupling of 2 aryl halides in presence of sodium metal in dry ethereal solution.

Which reaction gives acetoacetic ester as the product?

Condensation Reactions of Carbonyl Compounds The Claisen condensation of ethyl acetate yields ethyl acetoacetate. This readily available compound and other β-keto esters formed by Claisen condensations are used as intermediates in the synthesis of alkyl derivatives of ketones.
