실험 절차

2,8-dibromo-dibenzo[b,d]thiophene (14 g), phenylboronic acid (11.0 g) tetrakis(triphenylphosphine)palladium (3.8 g) and potassium carbonate (20 g) were refluxed together in a mixture of toluene (110 mL), ethanol (20 mL) and water (90 mL) overnight. The reaction was quenched with water and the toluene layer was removed and passed through a celite column and the toluene layer was evaporated in a rotary evaporator to yield 6.0 g 2,8-diphenyl-dibenzo[b,d]thiophene.
