Table 2. Applicability Study of α-(Hetero)Aryl Amines.
Reaction conditions: ammonium salt (1) (0.15 mmol, 1.0 equiv), NiBr2·(diglyme) (12 mol %), L3 (15 mol %), CO2/NH3 (15/15 mL), Zn (1.2 equiv), ZnF2 (50 mol %), NMP:diglyme (0.5:0.1 mL), 120 °C, 28 h. Isolated yields.
NiBr2 (12 mol %), dppe (12 mol %), NMP:toluene (0.5:0.1 mL), 120 °C, 24 h. Isolated yields.
GC yields reported using n-tetradecane as the internal standard.
30 h. rr represents the ratio of the major product to the sum of all other isomers as determined by GC analysis.
