N-Iodosuccinimide → 9-([1,1'-Biphenyl]-4-yl)-3-iodo-9H-carbazole

Participants

Reaction Steps

3.2 g (10 mmol) of 9-(4-biphenylyl)carbazole was dissolved in a mixed solution of 200 mL of glacial acetic acid, 200 mL of toluene, and 50 mL of ethyl acetate. 2.3 g (10 mmol) of N-iodosuccinimide was slowly added thereto. The mixture was stirred overnight (for about 24 hours) and then washed with water, a sodium thiosulfate water solution, and a saturated sodium chloride solution. Magnesium sulfate was added thereto to remove water and filtered to obtain a filtrate. The filtrate was concentrated, mixed with acetone and hexane, and then recrystallized with ultrasonic wave. This was filtered to obtain a residue. The residue was collected and dried. 4.4 g (yield: 98%) of 3-iodo-9-(4-biphenylyl)carbazole, which was beige powder, was obtained.
