Table 3. Tandem C–H Fluorination and S_NAr^a.

^aIsolated yields from the two-step sequence for reactions performed with 0.2 mmol of heteroarene. Yields in parentheses were determined by ¹⁹F NMR spectroscopy for the independent fluorination reaction.

^bThe isolated product contained ∼5% of an inseparable impurity.

^cThe Boc group was cleaved during the S_NAr reaction.
