Applications

3-Chloroperoxybenzoic acid is a strong oxidizing agent used in the oxidation reactions such as aldehydes and ketones to esters (Bayer-Villiger-Oxidation), olefines to epoxides, sulfides to sulfoxides and sulfones, and amines to nitroalkanes, N-oxides.

Notes

Heat sensitive. Incompatible with reactive with reducing agents, combustible materials, organic materials and alkalies.

Reagent for epoxidation of alkenes: J. Org. Chem., 29, 1976 (1964). Dichloromethane has been recommended as solvent for these reactions, since the peracid is soluble, but the by-product, 3-chlorobenzoic acid, is almost insoluble. For high-yield, stereospecific epoxidation in a two-phase, almost neutral system, see: J. Org. Chem., 44, 1351 (1979). For regioselective epoxidation of the more substituted double bond of a diene, see: Org. Synth. Coll., 5, 467 (1973). For epoxidation in aqueous solution followed by in situ hydrolysis to the trans-diol by 10% sulfuric acid, see: Synth. Commun., 19, 1939 (1989).

Carbonyl compounds undergo the Baeyer-Villiger reaction to give esters or lactones: J. Org. Chem., 29, 2914 (1964). For an extensive review of the Baeyer-Villiger reaction, see: Org. React., 43, 251 (1993).

Primary aliphatic amines are oxidized to nitro-compounds: J. Org. Chem., 31, 524 (1966). Good yields are obtained in 1,2-dichloroethane solution: J. Org. Chem., 44, 659 (1979); 54, 2869 (1989).

Sulfides can be oxidized selectively either to sulfoxides or sulfones: Tetrahedron, 22, 1235 (1966); J. Chem. Soc. (C), 2720 (1969); J. Org. Chem., 35, 2106 (1970).
