Substrate scope of aryl iodides bearing an electron-donating group. Conditions: 1 (0.3 mmol), 2 ( trans-configuration. 0.2 mmol), L3 (7.7 mol%), PdCl₂ (7 mol%), Cs₂CO₃ (2 eq), 4-NO₂PhCOOH (50 mol%), DME (2 mL), 60 °C, 24 h, unless otherwise noted. Isolated yields. The e.r. values were determined by HPLC using chiral columns. ^a90 °C. ^b5 mol% catalyst loading.
