Optimization of the defluorinative coupling of ArCF₃ with [1.1.1]propellane

^aPerformed with photocatalyst PCN (1) (10 mol%), trifluomethyl arene (5) (1.0 equiv.), [1.1.1]propellane in DMF (1.2 M, 1.5 equiv.), γ-terpinene (5.0 equiv.), Cs₂CO₃ (1.2 equiv.).

^bYield by ¹⁹F-NMR analysis of the crude reaction mixtures using PhCF₃ as internal standard
