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.

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. It has also been used in the preparation of mono- and di-epoxy-functionalized poly(3-hydroxybutyrate)-based reactive polymers. MCPBA is also an effective oxidizing agent for conversion of α-amide substituted polyesters to their corresponding polysulfones with tunable thermal properties.
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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
