Reaction Conditions:
with tris-(dibenzylideneacetone)dipalladium(0);tri-tert-butyl phosphine;sodium t-butanolate in 5,5-dimethyl-1,3-cyclohexadiene at 20; for 12 h;Reflux;Inert atmosphere;
Steps:
1
To the reaction flask3-Bromo-9-phenyl-9H-carbazole7.2 g (21.53 mmol),9H-carbazole3g (17.94 mmol),2.59 g (26.91 mmol) of sodium butoxide,Add 50 ml of xylene and stir at room temperature.0.5 g (0.54 mmol) of tris (dibenzylideneacetone) dipalladium (0)0.26 mL (0.54 mmol) of tri-tert-butylphosphine (50 wt%)And the mixture was refluxed under nitrogen flow for 12 hours.After completion of the reaction, the reaction mixture was slowly cooled to room temperature, and then the reaction solution was poured into a saturated aqueous solution of ammonium chloride and extracted with ethyl acetate.The organic layer was separated, dried over anhydrous magnesium sulfate and filtered.The filtrate was concentrated under reduced pressure and purified by column chromatography to obtain 5.8 g (80% by weight) of the target compound [2000] as a white solid.
