Substrate scope for the photoredox/nickel dual‐catalyzed arylalkylation of alkynes.^[a]

[a] Reaction conditions: aryl bromide (0.2 mmol), alkyl carboxylic acid (0.4 mmol), alkyne (0.6 mmol), Pc1 (0.002 mmol), NiBr₂ (0.02 mmol), Cs₂CO₃ (0.4 mmol) in DMF (2.0 mL) at room temperature under irradiation with a 34 W blue LED for 12 h. The values in parenthesss represent the ratio of syn‐addition product to anti‐addition product determined by ¹H NMR and NOESY analysis. [b] The reaction was performed on a 2.0 mmol scale.
