A palladium-catalyzed oxidative arylation of chromones was examined. A regioselective 2-arylation of chromone was carried out via a double C–Hactivationprocess. The procedure provided an expedient approach for the preparation of flavone derivatives.

Concise and selective: The title one‐pot sequence allows formation of the enone functionality and subsequent cross‐coupling. The process provides access to highly functionalized cyclic enolones and enaminones from readily accessible β‐heteroatom‐substituted cyclic ketones.
