Visible-Light-Promoted Oxidative Amidation of Bromoalkynes with Anilines: an Approach to Α-Ketoamides.

A convenient and practical synthetic route to α-ketoamides from bromoalkynes and anilines through phototriggered organic transformations via a C-N cross-coupling and an oxidation of C≡C was developed. The reaction could be furnished without an external photocatalyst at ambient conditions, and a wide range of α-ketoamides were obtained in good yields.
