실험 절차

Under the nitrogen atmosphere, triphenylen-2-ylboronic acid (5.6 g), 9-bromoanthracene (3.5 g), (Pd(PPh3)4) (0.5 g), potassium phosphate (5.8 g), and a mixture solvent of pseudo cumene, t-butyl alcohol, and water (48 ml) (pseudo cumene/t-butyl alcohol/water=10/1/1 (volume ratio)) were added to a flask and then refluxed for 8 hours. After adding water, the precipitates were collected by suction filtration. The obtained solid was washed with water followed by methanol and purified by silica gel column chromatography (solvent: toluene). After re-crystallization with a mixture solution of toluene/ethyl acetate, 2-(anthracen-9-yl)triphenylene (3.3 g) was obtained as an eleventh intermediate compound. The scheme is represented in the following “Reaction 21”.
