This reaction is carried out in the same manner as the reaction in example 3. The difference is that, the reactants are m-methoxyphenyl chloride (143.7 mg, 1.0 mmol), 1-(4′-fluorophenyl)ethanone (347.2 mg, 2.5 mmol), palladium cinnamyl chloride (7.8 mg, 0.015 mmol), 2-Methoxy-6-(N-methyl-N-phenyl-amino)phenyldicyclohexyl)phosphine (18.4 mg, 0.045 mmol), K3PO43H2O (664.2 mg, 2.5 mmol) in 3 mL dry toluene at 110° C. for 22.8 h. 1-(4′-Fluorophenyl)-2-(3′-methoxyphenyl)-1-ethanone (185.5 mg) was obtained with a yield of 75% as liquid. 1H NMR (300 MHz, CDCl3) δ 8.05-7.98 (m, 2H, ArH), 7.27-7.18 (m, 1H, ArH), 7.12-7.04 (m, 2H, ArH), 6.86-6.75 (m, 3H, ArH), 4.20 (s, 2H, CH2), 3.75 (s, 3H, OCH3); 13C NMR (75 MHz, CDCl3) δ 195.8, 167.2, 163.9, 159.7, 135.7, 132.8, 132.7, 131.2, 131.1, 129.6, 121.6, 115.7, 115.4, 115.0, 112.2, 55.0, 45.4; 19F NMR (282 MHz, CDCl3) 6-104.9; IR (neat) v (cm−1) 3072, 3002, 2940, 2836, 1682, 1597, 1506, 1491, 1455, 1437, 1331, 1264, 1232, 1157, 1099, 1050, 1002; MS (70 eV, EI) m/z (%): 245 (M++1, 3.27), 244 (M+, 17.36), 123 (100).
