Carboxylic acid reactions overview (article) Khan Academy

Carboxylic acid reactions overview (article) Khan Academy

Carboxylic acid reactions overview. Carboxylic acids belong to a class of organic compounds in which a carbon (C) atom is bonded to an oxygen (O) atom by a double bond and to a hydroxyl group (−OH) by a single bond. A fourth bond links the carbon atom to a hydrocarbon group (R). The carboxyl (COOH) group is named after the carbonyl group (C=O ...

Decarboxylation - CannaQAWiki

Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO 2).Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.The reverse process, which is the first chemical step in photosynthesis, is called carboxylation, the addition of CO 2 to a compound. Enzymes that …

Decarboxylation reaction. Decarboxylation is the loss of the acid functional group as carbon dioxide from a carboxylic acid. The reaction product is usually a halocompound or an aliphatic or aromatic hydrocarbon. The following illustration shows the sodalime method: Alipathic and aromatic acids can be decarboxylated using simple copper salts.

The decarboxylation reactions of metal carboxylates are of increasing value in the synthesis of organometallic compounds. The reverse reaction, for example, carbonation of Grignard and organolithium reagents, is a well-known source of carboxylic acids. The mechanisms of thermally initiated decarboxylations giving organometallic compounds have ...

Thiamin (Vitamin B 1) is the reagent used in living systems to catalyze decarboxylation reaction. Thiamin forms a ylid at biological pH. The ylid adds to the carbonyl group of pyruvate to give an intermediate that resembles a β -ketoacid, a β -iminoacid in this case, that easily decarboxylates. The thiamin intermediate is

decarboxylation of carboxylic acids and their salts

This reaction can be done with certain carboxylic acids themselves. For example, benzene can be made by heating soda lime with solid benzoic acid (benzenecarboxylic acid), C 6 H 5 COOH. You can think of this as first a reaction between the acid and the soda lime to make sodium benzoate, and then a decarboxylation as in the first example.
