YieldReaction ConditionsOperation in experiment
80% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,2-dimethoxyethane; water; at 90.0℃; for 16.0h;Inert atmosphere; To a sealed tube were added l -bromo-2,4,5-trichlorobenzene (3.0 g, 12 mmol), 1,2-dimethoxyethane: water ( 10 : 1 , 30 mL), (f)-2-(4-methoxystyryl)-4,4,5,5- tetramethyl- l,3,2-dioxaborolane (C6 4) (3.7 g, 14 mmol ), and potassium carbonate (3.2 g, 24 mmol) . The reaction mixture was degassed for 10 minutes with argon, followed by addition of tetrakis(triphenylphosphine)palladium(0) (0.55 g, 0.48 mmol) . The reaction mixture was degassed for 10 minutes then heated at 90 C for 16 hours. The reaction mixture was poured in to water and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated . Purification by flash column chromatography provided the title compound as an off-white solid (3.0 g, 80%) : NM R (400 MHz, CDC ) delta 7.73 (s, 1H), 7.50 - 7.45 (m, 3H), 7.20 (d, J = 16.0 Hz, 1 H), 7.02 (d, J = 16 Hz, 1H), 6.92 (d, J = 8.0 Hz, 2H), 3.84 (m, 3H) ; ESIMS m/z 313 ( [Mu + EtaGamma).
