and scalable methods for fluorination. The most straightforward route to synthesize aryl fluorides is through the halide exchange “halex” reaction, but conditions, cost, and atom economy preclude most available methods from large-scale manufacturing processes. We report a new approach that leverages the cooperative action of 18-crown-6 ether and tetramethylammonium chloride to catalytically access the
