A copper‐catalyzed C(sp)−C(sp3) cross‐coupling of terminalalkynes with readily available secondary α‐haloamides for the efficient synthesis of 2,3‐allenamides is realized. The methodology is characterized by its wide substrate scope, which makes it an important complement to traditional methods for synthesizing allenes. A mechanism involving an alkynylcopper species is proposed.
