YieldReaction ConditionsOperation in experiment
61% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In water; toluene; at 110℃; for 6h;Inert atmosphere; The same approach for synthesizing P1 was followed. P2 was prepared from intermediate 3 (0.30 g, 0.645 mmol)and <strong>[870774-25-7][4-(naphthalene-1-yl)phenyl]boronic acid</strong> (0.32 g,1.29 mmol). The crude product was purified through silica gel chromatography using petroleum ether/dichloromethane(5:1, v/v) as eluent to obtain desire product as white solid 0.28 g. Yield: 61%. Mp: 203-205 C. 1H NMR (400 MHz,DMSO-d6, delta, ppm): 8.54 (d, J = 8.0 Hz, 4H), 8.34 (s, 2H),8.13 (d, J = 7.2 Hz, 2H), 7.99-8.03 (m, 12H), 7.93 (d,J = 8.4 Hz, 2H), 7.53-7.66 (m, 15H). 13C NMR (101 MHz,DMSO-d6, delta, ppm): 156.0, 149.6, 140.3, 139.3, 138.9, 138.5,137.9, 137.6, 133.4, 130.7, 130.4, 129.3, 129.0, 128.3,127.7, 127.6, 127.3, 126.9, 129.8, 126.7, 126.4, 125.9,125.5, 125.2, 116.6. Anal. calcd. For C55H37N:C, 92.57; H,5.24; N, 1.97. Found C, 92.70; H, 5.19; N, 1.97.
