Copper‐bottomed catalysis! The direct alkynylation of azolesthrough a copper‐based CH bond activation, using alkynylbromides as the coupling partner, has been developed (see scheme). The method is very rapid, is functional‐group tolerant, and provides a straightforward entry to diverse alkynyl heterocycles that is complementary to the Sonogashira reaction.
