Abstract An alternative convenient approach for the bromination of various poly-substituted 4-pyridones has been developed via an oxidative nuclear bromination in the presence of sole pyridinium bromochromate (PBC). The PBC performs the dual role of oxidant and source of Br+ during the process. [Supplementary materials are available for this article. Go to the publisher's online edition of Synthetic
