Participants

Reaction Steps

Then in a stream of argon, 0.5 g (0.96 mmol) of the obtained 2-[3-chloro-5-(9-phenanthryl)phenyl]-4,6-diphenyl-1,3,5-triazine, 038 g (1.73 mmol) of 1-naphthaleneboronic acid, 12.9 mg (0.058 mmol) of palladium acetate and 1.13 g (3.46 mmol) of cesium carbonate were suspended in 50 mL of tetrahydrofuran, and the temperature of the obtained suspension was elevated to 70° C. and distilled under reflux for 40 hours. The resultant reaction mixture was cooled 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 purified by column chromatography to give 0.56 g of the target 2-[3-(1-naphthyl)-5-(9-phenanthryl)phenyl]-4,6-diphenyl-1,3,5-triazine as grayish white solid (yield: 95%).
