Reaction Conditions

Reaction Steps

Then, a mixed solution of 20.0 g of 1,3-dibromo-7-t-butylpyrene, 16.52 g of 4-chlorophenylboronic acid, 0.034 g of bis(triphenylphosphine)dichloropalladium, 106 ml of an aqueous 2M sodium carbonate solution and 240 ml of 1,2-dimethoxyethane was heated and stirred for about 5 hours under a nitrogen stream and under refluxing, and this was cooled to 5° C. After 240 ml of water was added, and the precipitated solid was filtered, the solid was washed with 125 ml of water two times and 125 ml of methanol once. After the solid was vacuum dried, the gray solid was dissolved in 48 ml of toluene, 2 g of active carbon was added, this was stirred for about 15 minutes, and the active carbon was filtered. After the resulting filtrate was evaporated, 100 ml of hexane was added, and the mixture was stirred for about 1 hour, and filtered. After the resultant was vacuum dried, 7.7 g of 7-t-butyl-1,3-bis(4-chlorophenyl)pyrene was obtained.
