Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
Carboxylation is a chemical reaction in which a carboxylic acid is produced by treating a substrate with carbon dioxide. [1] The opposite reaction is decarboxylation.In chemistry, the term carbonation is sometimes used synonymously with carboxylation, especially when applied to the reaction of carbanionic reagents with CO 2.
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...
From preformed carboxylic acid, the following routes have been demonstrated: [5] acid-base reactions: L n MOR' + RCO 2 H → L n MO 2 CR + R'OH protonolysis: L n Malkyl + RCO 2 H → L n MO 2 CR + alkane oxidative addition: L n M + RCO 2 H → L n (H)MO 2 CR. From preformed carboxylate, salt metathesis reactions are common: L n MCl + RCO 2 Na ...
Decarboxylation. 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.
Pivalic acid is produced from isobutene using the Koch reaction, [2] as well as several other branched carboxylic acids. An estimated 150,000 tonnes of "Koch acids" and their derivatives annually. [2] Koch–Haaf-type reactions have been used to carboxylate adamantanes. [3] [4] [5]
The reaction of fatty acids with base is the other main method of saponification. In this case, the reaction involves neutralization of the carboxylic acid. The neutralization method is used to produce industrial soaps such as those derived from magnesium, the transition metals, and aluminium.
The Varrentrapp reaction, also named Varrentrapp degradation, is a name reaction in the organic chemistry. It is named after Franz Varrentrapp, who described this reaction in 1840. [ 1 ] The reaction entails the degradation of an unsaturated carboxylic acid into a saturated acid with two fewer carbon atoms and acetic acid .
