Scope of photocatalytic C–X to C–D transformation^a

^a Reaction conditions: halides substrate (0.1 mmol), porous CdSe (5 mg), Na₂SO₃ (0.25 M), CH₃CN/D₂O (2.5 mL/1.5 mL), irradiation 8 h (>420 nm), r.t. For hydrodehalogenation, the reaction was conducted under UV light (>280 nm) for 2 h in CH₃CN/H₂O (2.5 mL/2.5 mL)

^b >420 nm, 12 h

^c isolated yield

^d 6 h, isolated yield

^e >420 nm, 6–8 h

^f 0.05 mmol of aryl iodides

^g 0.0375 mmol of aryl iodides, CdSe (7.5 mg), Na₂SO₃ (0.375 M)

^h 0.025 mmol of 1ab, 10 mg CdSe, 0.375 M Na₂SO₃, 6 h

ⁱ >280 nm, 12 h

^j >420 nm, 12 h

^k >280 nm, 10 h

^m conversion yields were reported. Yields (Error ca. 5%) were calculated from GC measurements using standard curve
