decarboxylation mechanism carboxylic acid
What is the mechanism of decarboxylation reaction of carboxylic acid?
Decarboxylation Reaction Mechanism
The decarboxylation mechanism replaces the carboxyl group in a carboxylic acid with hydrogen.
The reaction is facilitated by a group of enzymes called decarboxylases or carboxy-lyases.
The regent that helps with the reaction is Soda-lime.By decarboxylation of carboxylic acid (Laboratory method): When the sodium salt of a fatty acid is heated at 633K with sodalime (mixture of NaOH and CaO), a molecule of carbon dioxide is eliminated as carbonate and an alkane is formed.
What is the reaction mechanism of a carboxylic acid?
In general, carboxylic acids undergo a nucleophilic substitution reaction where the nucleophile (-OH) is substituted by another nucleophile (Nu).
The carbonyl group (C=O) gets polarized (i.e. there is a charge separation), since oxygen is more electronegative than carbon and pulls the electron density towards itself.
Which carboxylic acids decarboxylate easily?
β - keto acids are the carboxylic acids that undergo decarboxylation easily.
