Product 1

HCID 85977582Tert-butyl-rho-butyrylperbenzoate

Procedure

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.

Workup

  1. customis purified by chromatography over neutral aluminum oxide with dichloromethane-ether (5:1) as eluent
  2. customThe perester obtained
  3. waitsolidifies after several months in the refrigerator
