α-Haloamides are a very important class of carbonyl compounds, and widely exist in a range of natural products and bioactive molecules. Herein, the realization of the tandem oxidation/halogenation of ynamides by employing the zinc halide as both the catalyst and the halogen source is described, thus avoiding the use of other external halogenating reagents. This method allows the practical synthesis of a variety of valuable α-haloamides in moderate to good yields.

Key words: α-halo amides, oxidation, ynamide, tandem reaction
