“…Thus, a solution of the indicated electrophile in THF (1.0 mL) was added dropwise and the reaction mixture stirred for 12 h. The reaction was quenched with saturated aqueous NH 4 Cl (10 mL), the products were extracted with ethyl acetate (3 ϫ 10 mL), the extracts washed with brine, dried with MgSO 4 , and concentrated. 135.1, 131.3, 129.9, 129.3, 127.9, 127.7, 124.4, 78.9, 68.6 4 (0.8 mol-%, 4.5 mg) in THF (1 mL) and a solution of corresponding aryl halide RX (1 mmol, 2 equiv.) were added, and the resulting mixture was stirred at 60°C overnight.…”
