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,....
Alternately, it can be named as a "carboxy" or "carboxylic acid" substituent on another parent structure, such as 2-carboxyfuran. The carboxylate anion (R−COO − or R−CO − 2) of a carboxylic acid is usually named with the suffix -ate, in keeping with the general pattern of -ic acid and -ate for a conjugate acid and its conjugate base ...
For example, a carboxylic acid is defined as a carbonyl group (C=O) directly attached to a hydroxyl group (OH): O=C–OH. A vinylogous carboxylic acid has a vinyl unit (−HC=CH−, vinylene) between the two groups that define the acid: O=C–C=C–OH. The usual resonance of a
Carboxylate ions are essentially unreactive towards nucleophilic substitution, since they possess no leaving group. The reactivity of these five classes of compounds covers a broad range; the relative reaction rates of acid chlorides and amides differ by a factor of 10 13 .

anionic polymerization: An ionic polymerization in which the kinetic-chain carriers are anions. [ 1 ] In polymer chemistry , anionic addition polymerization is a form of chain-growth polymerization or addition polymerization that involves the polymerization of monomers initiated with anions .
An oxocarbon anion C x O n− y can be seen as the result of removing all protons from a corresponding acid C x H n O y. Carbonate CO 2− 3, for example, can be seen as the anion of carbonic acid H 2 CO 3. Sometimes the "acid" is actually an alcohol or other species; this is the case, for example, of acetylenediolate C 2 O 2− 2 that would ...
The Dakin oxidation. The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate.
