Reaction optimisation: electrolyses in undivided cell, ¹⁹F NMR yields. A) Yields of 3 a from 2 a (25 mm) in the presence of different aryl‐iodides (1) 4 F mol⁻¹. E _1/2 vs. Fc/Fc⁺. B) Yields of 4 (blue) and 3 a (green) from 1 a and 2 a (both 25 mm) in different HF:amine ratios after 4 F mol⁻¹. “Amine”=NEt₃ or py. C) Yields of 1 a after 4 F mol⁻¹, 12 mA (Pt∥Pt) in different amounts of HFIP in CH₂Cl₂. D) Fluorination of 2 as with and without Tol‐I. 4 F mol⁻¹ passed at 12 mA (Pt∥Pt).
