efficient and convenient rhodium catalyst system was developed for the title transformation. A base co‐catalyst was found to facilitate the key arene CH bond‐activation step and substrate scope was very broad, including both electron‐deficient pyridine N‐oxides, and electron‐rich azoles. The catalytic system was effective for the hydroheteroarylation of both alkenes and alkynes and gave excellent regio‐
