PROCEDURE

实验过程

A slurry of 14 g. (0.105 mole) of anhydrous aluminum chloride in 14.4 g. (0.150 mole) of fluorobenzene and 24 ml. of carbon disulfide is cooled to 15°C. To it is added 23.8 g. (0.100 mole) of α-bromoisobutyryl bromide over 10-15 minutes at 15°-20°C. The reaction is stirred for five minutes at 20°C and then quenched on ice. The product is extracted into chloroform. The chloroform layer is washed with aqueous sodium bicarbonate, dried over anhydrous sodium sulfate and concentrated to give 2-bromo-4'-fluoro-2-methylpropiophenone.
