Reaction Conditions

Reaction Steps

A mixed solution of 2 g of 1,6-dibromopyrene, 1.9 g of 4-methylphenylboronic acid, 5.9 g of tripotassium phosphate, 0.9 g of tetrabutylammonium bromide, 15 mg of palladium acetate and 30 ml of dimethylformamide was heated while stirred under nitrogen gas stream at a temperature of 130° C. for 6 hours. After cooling the mixed solution to room temperature, 30 ml of water was injected thereinto and the resulting solution was filtered. The solid filtered off was washed with 30 ml of ethanol, and thereafter recrystallized from toluene and vacuum dried to thereafter obtain 1.3 g of 1,6-bis(4-methylphenyl)pyrene.
