ChemInform Abstract: Effect of N‐Bromosuccinimide (NBS) and Other N‐Brominating Agents on the Bromination of α,β‐Unsaturated Ketones in Methanol.

Abstract When the α,β‐unsaturated ketones (I) are treated with bromine in methanol (II) in the absence or presence of NBS, a concurrency between bromination and methoxybromination is observed.
