The Koch reaction is an organic reaction for the synthesis of tertiary carboxylic acids from alcohols or alkenes and carbon monoxide.Some commonly industrially produced Koch acids include pivalic acid, 2,2-dimethylbutyric acid and 2,2-dimethylpentanoic acid. [1]
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
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 ...
Forming aldehydes from carboxylic acid derivatives is challenging because weaker reducing agents (NaBH 4) are often very slow at reducing esters and carboxylic acids, whereas stronger reducing agents (LiAlH 4) immediately reduce the formed aldehyde to an alcohol. [10] Conversion to thioester followed by Fukuyama reduction
Azelaic acid and pelargonic acids are produced from ozonolysis of oleic acid on an industrial scale. An example is the ozonolysis of eugenol converting the terminal alkene to an aldehyde: [9] By controlling the reaction/workup conditions, unsymmetrical products can be generated from symmetrical alkenes: [10]
An α,β-unsaturated acid is a type of α,β-unsaturated carbonyl compound that consists of an alkene conjugated to a carboxylic acid. [3] The simplest example is acrylic acid (CH 2 =CHCO 2 H). These compounds are prone to polymerization, giving rise to the large area of polyacrylate plastics.
The Pinnick oxidation is an organic reaction by which aldehydes can be oxidized into their corresponding carboxylic acids using sodium chlorite (NaClO 2) under mild acidic conditions. It was originally developed by Lindgren and Nilsson. [1] The typical reaction conditions used today were developed by G. A. Kraus.
Jones reagent will convert primary and secondary alcohols to aldehydes and ketones, respectively. Depending on the reaction conditions, the aldehydes may then be converted to carboxylic acids. For oxidations to the aldehydes and ketones, two equivalents of chromic acid oxidize three equivalents of the alcohol:
