A mild and efficient mono-selective bromination of 1,3-dicarbonylcompounds has been developed using lipophilic indole catalysts. Inexpensive and commercially available N-bromosuccinimide (NBS) was used as the brominating reagent. The selectivity was further enhanced when using stoichiometric amount of 3-bromoindole species. Mechanistic studies reveal that the indole catalyst has dual functions in
