With N2;tris-(dibenzylideneacetone)dipalladium(0); Pd2(dba)3; In tetrahydrofuran; 5,5-dimethyl-1,3-cyclohexadiene; hexane; dichloromethane; toluene; | A mixture of 9-phenyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9H-carbazole (12 g, 32.5 mmol), 3-bromo-9H-carbazole (6.66 g, 27.1 mmol), and potassium phosphate (34.5 g, 162 mmol) in 500 mL of toluene and 50 mL of H2O was bubbled with N2 for 20 min. Dicyclohexyl(2',6'-dimethoxybiphenyl-2-yl)phosphine (0.445 g, 1.083 mmol) and Pd2(dba)3 (0.248 g, 0.271 mmol) were then added, and the mixture was heated to reflux under N2 for 5 h. TLC indicated the reaction was done. The reaction was extracted with dichloromethane and washed with brine and dried with magnesium sulfate. The solution was heated up to boil. Hexane was added. The dichloromethane was boiled off and hexanes volume reached about 1200 mL. Precipitate formed during boiling off dichloromethane. The solution was cooled to room temperature and stirred overnight. The precipitate was filtered and dissolved in THF and ran a short silica gel plug. After dried under vacuum at 60 C., 9.6 g (87%) of product was obtained. Synthesis of Compound 1. A mixture of <strong>[5408-56-0]2-iododibenzo[b,d]furan</strong> (2.59 g, 8.81 mmol), 9-phenyl-9H,9'H-3,3'-bicarbazole (3 g. 7.34 mmol), and sodium t-butoxide (1.764 g, 18.36 mmol) in 200 mL of xylene was bubbled with N2 for 20 min. Dicyclohexyl(2',6'-dimethoxybiphenyl-2-yl)phosphine (0.121 g, 0.294 mmol) and Pd2(dba)3 (0.067 g, 0.073 mmol) were then added, and the mixture was heated to reflux under N2 for 24 h. The mixture was cooled and filtered through Celite. After solvent evaporation, the residue was coated on Celite and purified by column chromatography 3.7 g of product was obtained after column. |
