A robust one-step synthesis of ynamides from vinyl dichlorides and electron deficient amides as cheap and easily available starting materials proceeds under mild reaction conditions in open air In the absence of a transition-metal catalyst. This strategy is not only suitable for the synthesis of both terminal and internal ynamides but also amenable for large-scale preparation.
