摘要：

The first example of direct C-H alkynylation of electron-rich heteroaromatics has been demonstrated. This mild, simple, and general method allows for the efficient synthesis of diverse alkynyl heterocycles. Kinetic isotope effect studies support an electrophilic substitution pathway for this transformation.
