title: A mild and efficient procedure for alpha-bromination of ketones using N-bromosuccinimide catalysed by ammonium acetate.
abstract: Cyclic ketones reacted with N-bromosuccinimide (NBS) catalysed by NH(4)OAc in Et(2)O at 25 degrees C to give the corresponding alpha-brominated ketones in good yields, while acyclic ketones were efficiently brominated in CCl(4) at 80 degrees C.
