Oxidation of Aldehydes to Carboxylic Acids
Oxidation of Aldehydes to Carboxylic Acids: Autoxidation
Aldehydes have the tendency to react with atmospheric oxygen to form carboxylic acids. This reaction is called autoxidation described by the following mechanism.
First, a radical chain reaction takes place in which the aldehyde is transformed into the corresponding peracid.
The peracid subsequently reacts with the aldehyde in a Baeyer-Villiger oxidation to yield two carboxylic acids.
