Sodium Iodide → 9-(3'-iodo-[1,1'-biphenyl]-3-yl)-9H-carbazole

Participants

Reaction Steps

9-(3′-bromo-[1,1′-biphenyl]-3-yl)-9H-carbazole (9.50 g, 23.85 mmol), sodium iodide (7.15 g, 47.7 mmol), copper(I) iodide (1.363 g, 7.16 mmol), and dioxane (239 ml) were added into a 500 mL 3-necked flask. N1,N2-dimethylcyclohexane-1,2-diamine (1.881 ml, 11.93 mmol) was added. The reaction mixture was heated and refluxed overnight. After completion of the reaction, the reaction mixture was cooled to room temperature. The reaction mixture was filtered through a pad of Celite® and washed several times with DCM. The solvent are evaporated in vacuum. The crude material was purified by column chromatography using hexane and DCM (75/25) and gradually increasing DCM to a ratio of hexane/DCM 50/50. The product was further purified by trituration from methanol. 9-(3′-iodo-[1,1′-biphenyl]-3-yl)-9H-carbazole (10.2 g, 22.91 mmol, 96% yield) was obtained as a white solid.
