The first general examples of direct coupling of heteroaryl chlorides, especially substituted 2‐pyridyl chlorides which were previously found to be problematic, with electron‐deficient polyfluoroarenes are reported. Pd(OAc)2 associated with 3‐(dicyclohexylphosphino)‐2‐phenylindole L1 serves as the effective catalyst which allows the challenging direct coupling of heteroaryl chlorides and polyfluoroarenes
