Various carbonyl compounds undergo alpha-bromination reaction under a mild and practical condition utilizing N-bromosuccinimide (NBS), catalyzed by trimethylsilyl trifluoromethanesulfonate ((TMSOTf)-O-.). This method is also effective for the side-chain bromination of heteroaromatic carbonyl compounds without the ring brominations. (c) 2005 Elsevier Ltd. All rights reserved.
