Bromobenzene → [1,1'-Biphenyl]-3-carbonitrile

참여 물질

반응 단계

To a solution of 3-cyanophenylboronic acid (1.0 g, 6.81 mmol) and bromobenzene (1.07 g, 6.81 mmol) in N,N-dimethylformamide (100 mL) were added tetrakis(triphenylphosphine)palladium(0) (0.393 g, 0.341 mmol) and cesium carbonate (2.77 g, 8.51 mmol) under nitrogen atmosphere, and the mixture was stirred for 4 hours under reflux. The reaction mixture was allowed to room temperature, ethyl acetate and water were added for partitioning, the organic layer was washed with water and dried over anhydrous magnesium sulfate. The solvent was evaporated, the residue was purified by silica gel column chromatography (hexane:ethyl acetate=10:1), and biphenyl-3-carbonitrile (821 mg, 67%) was obtained as a yellow solid.
