Take five: A new method employing aryl halide carbonylation to directly access heterocycles has been described (see scheme). In a single palladium‐catalyzed reaction the catalyst mediates two consecutive carbonylation steps, thereby converting five components (aryliodide, two units imine, and two units CO) into an imidazoline ring.
