実験手順

A degassed solution of 24.6 g (87 mmol) of 1-bromo-4-iodobenzene and 28.8 g (80 mmol) of biphenyl-4-yl-(9,9-dimethyl-9H-fluoren-2-yl)amine in 1000 ml of dioxane is saturated with N2 for 1 h. Then firstly 0.9 ml (4.3 mmol) of P(tBu)3, then 0.48 g (2.1 mmol) of palladium(II) acetate are added to the solution. 12.6 g (131 mmol) of NaOtBu in the solid state are subsequently added. The reaction mixture is heated under reflux for 18 h. After cooling to room temperature, 1000 ml of water are carefully added. The organic phase is washed with 4×50 ml of water and dried over MgSO4, and the solvent is removed in vacuo. The pure product is obtained by recrystallisation and final sublimation.
