Bromine → 2-Bromo-1-(4-chloro-3-nitrophenyl)ethan-1-one

Participants

Reaction Steps

In a 500 mL round-bottomed flask was added 1-(4-chloro-3-nitrophenyl)ethanone (11.98 g, 60 mmol) in benzene (75 ml) to give a white suspension. Bromine (9.59 g, 60.0 mmol) was added dropwise over 5 minutes to give a deep red solution. Stirred for 1 hour to give a yellow solution that was concentrated in vacuo to a yellow solid. Recrystallized from 9:1 hexane/ethyl acetate to give 2-bromo-1-(4-chloro-3-nitrophenyl)ethanone as yellow needles.
