YieldReaction ConditionsOperation in experiment
0.9 g With bis-triphenylphosphine-palladium(II) chloride; potassium hydroxide; In tetrahydrofuran; water; at 80℃; for 24h;Inert atmosphere; 1g (2.6 mmol) of 2,7-dibromo-9,9-diethylfluorene (2), 1 g (5.7 mmol) of <strong>[182482-25-3]2,4,6-trifluorophenyl boronic acid</strong>, 0.07 g (0.09 mmol)of PdCl2(PPh3)2 and 0.7 g (13.0mmol) of powdered potassiumhydroxidewere stirred in 15mlof THF containing degassed water (1.5ml) at 80C under nitrogen for 24 h. After TLC controlthe reaction mixture was cooled and quenched by the addition of ice water. The product wasextracted by ethyl acetate. The combined extractwas dried over anhydrousNa2SO4. The crudeproduct was purified by silica gel column chromatography using the mixture of ethyl acetateand hexane (vol. ratio 1:3) as an eluent. Yield: 0.9 g of brown crystals. M.p.: 152C (DSC).MS (APCI+, 20 V): 483.1 ([M + H], 100%). 1H NMR (300 MHz, CDCl3, delta, ppm): 7.52-7.50 (m, 4H, Ar), 7.47-7.42 (m, 6H, Ar), 1.98 (q, 4H, J = 7.5Hz, 2 × CH2CH3), 0.31 (tr, 6H,J = 7.5Hz, 2 × CH2CH3).
