YieldReaction ConditionsOperation in experiment
40% With sodium hydride; In tetrahydrofuran; mineral oil; at 0 - 60℃; for 15.5h; To a mixture of 1 ,2,4,5- tetrafluoro-3,6-bis(trifluoromethyl)benzene (0.286 g, 1 .0 mmol) (Synquest Laboratory, Alachua, FL), 3,6,-diphenyl-9/-/-carbazole (1 .5 g, 4.5 mmol) (TCI America, Portland, OR) in anhydrous tetrahydrofuran (THF) (15 mL) (Aldrich, St Louis, MO), was added sodium hydride (60percent in mineral oil, 0.20 g, 5 mmol) (Aldrich) at 0 °C. The resulting mixture was stirred at 0 °C for 30 min, then 60 °C for 15 hours on a hot plate with a silicone oil bath. Yellow precipitate formed, and the mixture was diluted with 200 mL of THF, washed with brine, dried over Na2S04 (Aldrich), loaded on silica gel (Aldrich, Grade 135) and purified by flash column using eluents of dichloromethane/hexanes (30percent to 60percent) (Aldrich). The desired fractions were collected, concentrated and filtered to give a yellow solid (EC-1 ) (0.57 g, in 40percent yield). Confirmed by liquid-chromatograph-mass-spectrometer (LCMS) (using atmospheric pressure chemical ionization [APCI]) (Shimadzu Scientific Instruments, Tokyo, Japan): calculated for C 04H65F6N4 (M+H): 1483; found: 1483.
