tert-Butyl 4-benzoylbenzene-1-carboperoxoate → Tert-butyl-rho-butyrylperbenzoate

Participants

Reaction Steps

Tert-butyl-ρ-butyrylperbenzoate is prepared by the above-discussed procedure for the preparation of t-butyl-4-benzoylperbenzoate, except that the acid employed is ρ-butyryl benzoic acid and is purified by chromatography over neutral aluminum oxide with dichloromethane-ether (5:1) as eluent. The perester obtained is a yellow oil which solidifies after several months in the refrigerator.
