Participants

Reaction Steps

In a stream of argon, 1.37 g (6.16 mmol) of 9-phenanthreneboronic acid, 1.20 g (2.57 mmol) of 2-(3,5-dibromophenyl)-4,6-diphenyl-1,3,5-triazine and 72.1 mg (0.103 mmol) of dichlorobis(triphenylphosphine)palladium were suspended in 75 mL of tetrahydrofuran, and the temperature of the obtained suspension was elevated to 70° C. 4.81 mL (19.3 mmol) of an aqueous 4N NaOH solution was gradually added dropwise to the suspension, and the obtained mixture was distilled under reflux for 5 hours. The resultant reaction mixture was left to stand to room temperature, and then distilled under a reduced pressure to remove all volatile materials. Methanol was added to the concentrate, and the thus-deposited solid was collected by filtration. The thus-obtained crude product was recrystallized from o-xylene to give 1.13 g of the target 2-[3,5-di(9-phenanthryl)phenyl]-4,6-diphenyl-1,3,5-triazine as grayish white solid (yield: 66%).
