Optimization of reaction conditions for nickel-catalyzed reductive aryl-thiolation

Reaction conditions: 1a (0.2 mmol, 1.0 equiv.); 2a (0.22 mmol, 1.1 equiv.); [Ni] (5.0 mol%); ligand (7.5 mol%); Mn (0.3 mmol, 1.5 equiv.); DMF (1 mL); N₂ atmosphere; 30 °C; 5 h

*Yields were determined by GC with tridecane as the internal standard

^†Zn powder (1.5 equiv.) instead of Mn powder was used
