Copper-Catalyzed Alkynylation of Amides with Potassium Alkynyltrifluoroborates: A Room-Temperature, Base-Free Synthesis of Ynamides
An efficient copper-mediated method for the coupling of potassium alkynyltrifluoroborates with nitrogen nucleophiles is reported. This reaction provides the first base-free and room-temperature synthesis of ynamides and allows for an easy preparation of these useful building blocks.info:eu-repo/semantics/publishe
