9-(4-Bromophenyl)carbazole → 3-(4-Carbazol-9-ylphenyl)-8,8-dimethyl-8H-10,12b-diazabenzo[a]-aceanthrylene

Participants

Reaction Steps

The compound is synthesised by the same procedure as Example 7 by reaction of 36 g (110 mmol) of 8,8-dimethyl-8H-10,12b-diazabenzo[a]aceanthrylene-3-boronic acid with 35.4 g (110 mmol) of 9-(4-bromophenyl)-9H-carbazole. The residue is recrystallised from toluene and from CH2Cl2/isopropanol and finally sublimed in a high vacuum. Yield: 47 g (99 mmol), 82% of theory, purity according to HPLC 99.9%.
