実験手順
1 ml of hydrogen bromide/glacial acetic acid is added to 65.5 g (0.36 mole) of 4-chlorophenyl isopropyl ketone in 200 ml of chloroform and then 57.5 g (0.36 mole) of bromine is added dropwise at 30° C. The mixture is allowed to stir at room temperature for 30 minutes and then evaporated in vacuo. 86.6 g (92% of theory) of crude 2-bromo-2-propyl 4-chlorophenyl ketone are obtained, which is immediately reacted further.
