Table 2: Scope of Phenol Nucleophiles.

Standard conditions: 1 (1.0 equiv., 0.50 mmol), 5a–o (5.0 equiv., 2.5 mmol), TBD (0.50 equiv., 0.25 mmol), DCB (0.50 M, 1.0 mL), 140 °C, for 24 h under an N₂ atmosphere. The selectivity of 6:7 was determined by ¹⁹F NMR analysis of the crude reaction mixture using TFT (50 μL) as a standard and is reported in parentheses. Yields are reported as the isolated yield of >95% pure material and represent the average of 2 runs. [a] 1.0 equiv. TBD. [b] Contains trifluoroethylbenzene side product.
