Extended Data Fig. 4: Deuterodehalogenation.

Standard conditions: Undivided cell, Al (+), Ru-N/CF (−) (Ru 3 mol%), e 0.4 mmol, ⁿBu₄NBr 0.8 mmol, ^tBuOD/D₂O = 5.0/5.0 mL, constant current, 10 mA, room temperature, argon atmosphere, 20 h to 72 h, isolated yield. ^anBu₄NBr 0.4 mmol, ^tBuOD/D₂O = 2.5/2.5 mL, t = 8 h to 20 h. ^bThe position of halogen in the substrates with the number less than five. ^cRu-N/CF-2 (Ru 5 mol%) was used. ^dD-incorporation (and yield) was determined by product benzoylation. ^ePentafluorophenylacetonitrile was used as substrate.
