This reaction is carried out in the same manner as the reaction in example 3. The difference is that, the reactants are p-methoxyphenyl chloride (142.3 mg, 1.0 mmol), 1-(2-fluorophenyl)-1-propanone (304.2 mg, 2.0 mmol), palladium acetate (6.8 mg, 0.030 mmol), 2-Methoxy-6-(N-methyl-N-phenyl-amino)phenyl(dicyclohexyl)phosphine (18.4 mg, 0.045 mmol), t-BuONa (192.7 mg, 2.0 mmol) in 3 mL dry toluene at 110° C. for 41.5 h. 1-(2′-Fluorophenyl)-2-(4′-methoxyphenyl)-1-propanon (134.7 mg) was obtained with a yield of 52% as liquid. 1H NMR (300 MHz, CDCl3) δ 7.76-7.68 (m, 1H, ArH), 7.44-7.34 (m, 1H, ArH), 7.20-7.08 (m, 3H, ArH), 7.07-6.98 (m, 1H, ArH), 6.83-6.77 (m, 2H, ArH), 4.57 (q, J=6.9 Hz, 1H, CH), 3.73 (s, 3H, OCH3), 1.52 (d, J=6.9 Hz, 3H, CH3); 13C NMR (75 MHz, CDCl3) δ 199.8 (d, J=3.8 Hz), 160.7 (d, J=251.9 Hz), 158.5, 133.8 (d, J=8.8 Hz), 132.3, 130.9 (d, J=2.8 Hz), 129.1, 126.0 (d, J=12.8 Hz), 124.2 (d, J=3.9 Hz), 116.4 (d, J=23.7 Hz), 114.0, 55.0, 50.9 (d, J=5.9 Hz), 18.8; 19F NMR (282 MHz, CDCl3) 6-100.1; IR (neat) v (cm−1) 3069, 3034, 2974, 2933, 2871, 2836, 1682, 1609, 1582, 1513, 1480, 1451, 1422, 1373, 1324, 1303, 1274, 1254, 1211, 1179, 1153, 1105, 1034, 1005; MS (70 eV, EI) m/z (%): 259 (M++1, 0.99), 258 (M+, 5.49), 135 (100); HRMS calcd for C16H15O2F (M+): 258.1056.
