Reaction Steps

7.1 g (9.0 mmol) of 4-(7-bromo-12,12-dimethyl-10,12-dihydro-10-azaindeno[2,1-b]fluoren-10-yl)-4′-(12,12-dimethyl-10,12-dihydro-10-azaindeno[2,1-b]fluoren-10-yl)biphenyl, 2.5 g (9.85 mmol) of bis(pinacolato)diborane and 2.6 g (26 mmol) of potassium acetate are suspended in 500 ml of dioxane. 0.22 g (0.27 mmol) of 1,1-bis(diphenylphosphino)ferrocenepalladium(II) dichloride complex with dichloromethane is added to this suspension. The reaction mixture is heated under reflux for 16 h. After cooling, the organic phase is separated off, washed three times with 150 ml of water and subsequently evaporated to dryness. The residue is recrystallised from toluene. The yield is 6.8 g (8 mmol, 90%).
