9,9-Dimethyl-9H-fluoren-2-amine → 9,9-Dimethyl-N-(4-(9-phenyl-9H-carbazol-3-yl)phenyl)-9H-fluoren-2-amine

Participants

Reaction Steps

50 g (112 mmol) 3-(4-Iodo-phenyl)-9-phenyl-9H-carbazole and 23.5 g (112 mmol) 9,9-Dimethyl-9H-fluoren-2-ylamine are dissolved in 500 ml toluene and 21.5 g sodium-tert-butylat is added. The reaction mixture is carefully degassed and 80 mg bis(diphenylphosphino)ferrocendichloro-Pd(II) (Pd(dppf)) complex is added. The solution is refluxed for 6 h. The reaction mixture is then cooled to room temperature and 250 ml water are added. The layers are separated. The water phase is extracted three times with toluene, and then the organic layers is washed twice with water dried over magnesium sulphate, filtrated and the solvent is removed under vacuum. The residue is recrystallized from butanole, to yield 57 g (108 mmol) (96%) of a white solid with a purity of 99.5%.
