The Kolbe reaction is formally a decarboxylative dimerisation of two carboxylic acids (or carboxylate ions). The overall reaction is: If a mixture of two different carboxylates are used, all combinations of them are generally seen as the organic product structures: 3 R 1 COO − + 3 R 2 COO − → R 1 −R 1 + R 1 −R 2 + R 2 −R 2 + 6 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 ...
Dimers of carboxylic acids are often found in the vapour phase. Anhydrous carboxylic acids form dimers by hydrogen bonding of the acidic hydrogen and the carbonyl oxygen. For example, acetic acid forms a dimer in the gas phase, where the monomer units are held together by hydrogen bonds. [3] Many OH-containing molecules form dimers, e.g. the ...
Some important classes of organic molecules are derivatives of alkanes, such as the primary alcohols, aldehydes, and (mono)carboxylic acids form analogous series to the alkanes. The corresponding homologous series of primary straight-chained alcohols comprises methanol (CH 4 O), ethanol (C 2 H 6 O), 1-propanol (C 3 H 8 O), 1-butanol, and so on.
Arndt–Eistert reaction is a series of chemical reactions designed to convert a carboxylic acid to a higher carboxylic acid homologue (i.e. contains one additional carbon atom) Kowalski ester homologation, an alternative to the Arndt-Eistert synthesis. Has been used to convert β-amino esters from α-amino esters through an ynolate ...
Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives. Citric acid. If there are multiple carboxyl groups on the same parent chain, multiplying prefixes are used: Malonic acid, CH 2 (COOH) 2, is systematically named propanedioic acid. Alternatively, the suffix ...
Ketonic decarboxylation (also known as decarboxylative ketonization) is a type of organic reaction and a decarboxylation converting two equivalents of a carboxylic acid (R−C(=O)OH) to a symmetric ketone (R 2 C=O) by the application of heat. It can be thought of as a decarboxylative Claisen condensation of two identical molecules.
