Procedure

1.23 g (3.5 mmol) of the triphenylene moronic ester from the previous step, 0.5 g (1.5 mmol) of 1,3-diiodobenzene, 1.0 g (7.5 mmol) of potassium carbonate, 30 mL of toluene, and 10 mL of water was mixed in a 250 mL three-neck flask. The system was purged by nitrogen for 10 min before adding 0.05 g of Pd(PPh3)4. The mixture was then heated up to 87° C. with vigorous stirring. After 24 hr, to the mixture was added 200 mL of methanol. The precipitate was collected by filtration. The solid was washed with copious amount of methanol, then hexanes. The solid was then recrystallized from 80 ml of xylenes. Final purification of the product involved subliming the material at 250° C. 0.35 g product was collected as white needle crystals.
