An efficient and stereoselective protocol has been developed for the synthesis (Z)‐β‐Halogenated enamide via gold catalyzed Ritter reaction. In the presence of 2 mol‐% BrettPhosAuCl and 2 mol‐% AgNTf2, a broad range of nitriles smoothly underwent Ritter reaction with aromatic, vinylic or aliphatic haloalkynes to give structurally diverse (Z)‐β‐Halogenated enamides in excellent to good yields.
