Participants

Reaction Steps

6.0 g (7.0 mmol) of 4-(7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-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, 1.9 g (7.1 mmol) of 2-chloro-4,6-diphenyl-1,3,5-triazine and 0.83 g (7.8 mmol) of sodium carbonate are suspended in 400 ml of dioxane, 400 ml of toluene and 200 ml of water. 0.42 g (3.6 mmol) of Pd(PPh3)4 is added to this suspension. The reaction mixture is heated under reflux for 5 h. After cooling, the precipitated solid is filtered off with suction, washed with water and ethanol and dried. The residue is extracted with hot toluene, recrystallised from toluene and finally sublimed in a high vacuum. The yield after sublimation is 5.2 g (5 mmol, 77%) with a purity of 99.9%.
