Participants

Reaction Steps

A mixture of 2,3-dichloro-6-propenyl-4-(2-fluorobenzoyl)phenol (62.5 g., 0.192 mole) and m-chloroperoxybenzoic acid (47.6 g., 0.22 mole) in 550 ml. of methylene chloride was stirred at room temperature for 24 hours. The precipitated m-chlorobenzoic acid was removed by filtration and the filtrate was washed successively with 5% aqueous sodium sulfite and 10% aqueous sodium bicarbonate. The methylene chloride was kept at room temperature for 4 days and then washed with 0.5N NaOH solution. After drying over MgSO4, the solvent was evaporated to give 45 g. of solid product, m.p. 148°-150° C.
