Answers
[93-59-4] · C7H6O3 · Perbenzoic Acid · (MW 138.13)
(electrophilic reagent capable of delivering oxygen to alkenes,1 amines,2 and sulfides3)
Alternate Name: peroxybenzoic acid; PBA.
Physical Data: mp 41-42 °C.
Solubility: sol CHCl3, CH2Cl2, benzene, ethyl acetate, ether; slightly sol water.
Form Supplied in: long white needles, but usually handled in solution; not available commercially.
Analysis of Reagent Purity: iodometric assay.4,6
Preparative Methods: Sodium Methoxide reacts readily with Dibenzoyl Peroxide (1) (eq 1); complete experimental details are available for preparing perbenzoic acid based on this reaction.4 Alkaline perhydrolysis (HOO-) of (1) in aqueous organic solvents has been employed for preparing PBA in 90% yields.5 PBA has been prepared in 85-90% yield by adding 70% Hydrogen Peroxide (Caution!) to a suspension of benzoic acid (2) in methanesulfonic acid (eq 2).6 PBA has been prepared in 90% yield by passing oxygen containing catalytic quantities of ozone through a solution of benzaldehyde in ethyl acetate.7
Purification: PBA can be purified by recrystallization at -20 °C from a 3:1 mixture of petroleum ether-diethyl ether.
Handling, Storage, and Precautions: analytically pure PBA can be stored for long periods in a refrigerator without significant loss of active oxygen. Since PBA is a peroxide and potentially explosive, care must be exercised in carrying out the reactions with it; during workup, check for peroxides before evaporating the solvent. This reagent
