An efficient approach for alpha-bromination of aryl alkyl ketones, utilizing a system consisting of aqueous hydrobromic acid as bromine source, sodium nitrite-KI as catalyst, and air as terminal oxidant, has been developed. The method offers advantages of selective monobromination, mild reaction conditions, broad substrate scope, and good yield. The use of air as the terminal oxidant makes the reaction very attractive from both economical and environmental viewpoints. (C) 2016 Elsevier Ltd. All rights reserved.
