Yields determined by ¹⁹F NMR integration relative to fluorobenzene internal standard over a 12 h time frame in neat substrate.

^a0.1 mol% catalyst loading for 36 h.

^b5.0 mol% catalyst loading.

^c0.5 mol% catalyst loading.

^dDue to overlapping C–F resonances, the yield was determined by ¹H NMR integration relative to an internal standard of fluoroanisole.
