General description

3-Chloroperbenzoic acid is a strong oxidizing agent mainly used for the epoxidation of alkenes and also in the Baeyer-Villiger oxidation of ketones to esters.[1][2]

Application

3-Chloroperbenzoic acid has been used in the oxidation of N-p-tolylsulfinyl-(E)-1-phenylethylideneimine to N-p-tolylsulfonyl (E)-1-phenylethylideneimine using dichloromethane as a solvent.[3] It has also been used in the preparation of mono- and di-epoxy-functionalized poly(3-hydroxybutyrate)-based reactive polymers.[4] MCPBA is also an effective oxidizing agent for conversion of α-amide substituted polyesters to their corresponding polysulfones with tunable thermal properties.[5]
Effective oxidant for epoxidizing di-, tri-, and tetra-substituted olefins.

    Baeyer-Villiger Oxidation Reaction

    The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
