Baeyer-Villiger Oxidation Reaction

The Baeyer–Villiger reaction involves the oxidation of ketones to esters by C-C bond cleavage of the carbonyl group and the introduction of an oxygen atom adjacent to it.1 This reaction can be accomplished using hydrogen peroxide, 3-chloroperbenzoic acid (m-chloroperoxybenzoic acid), peroxyacetic acid, or peroxytrifluoroacetic acid as the oxidizing agent. This reaction is also useful in the synthesis of lactones (cyclic esters) from cyclic ketones.

Stereospecificity and predictable regiochemistry are important features of the Baeyer–Villiger oxidation reaction. The reaction is regiospecific in nature and depends on the relative migration ability of the substituents attached to the carbonyl group. This reaction was described by Adolf von Baeyer and Victor Villiger in 1899.

A chemical reaction diagram showing the conversion of a ketone (left) to an ester (right) using a peroxyacid (center). The ketone is represented with a carbonyl group (C=O) and two substituents (R1 and R2). The peroxyacid is shown with a peroxide linkage (–O–O–) and a hydroxyl group (–OH). The resulting ester is depicted with a carbonyl group and an ether linkage (–O–) connected to R1 and R2.

An example for Baeyer–Villiger oxidation reaction:

A chemical reaction diagram illustrating the transformation of cyclohexanone (left) into 6-hexanolactone (right) using 3-chloroperbenzoic acid (center) as the reagent. Cyclohexanone is depicted with a cyclic structure and a carbonyl group (C=O). The 3-chloroperbenzoic acid is shown with a benzene ring, a carboxylic acid group (–COOH), and a chlorine atom (Cl). The product, 6-hexanolactone, is represented with a cyclic structure featuring two carbonyl groups.
