Reaction Steps
2,2′-Diiodo-9,9′-spirobifluorene (2.84 g, 5.0 mmol), 4-(diphenylamino)phenylboronic acid (4.34 g, 15.0 mmol), Pd(PPh3)4 (0.289 g, 0.25 mmol), 2M K2CO3(aq) (25 ml) and tri-tert-butylphosphine (0.5 mmol) were mixed in a flask containing with toluene (50.0 mL). The mixture was refluxed 72 hours. The solution was extracted twice with chloroform. The combined organic extracts were dried (MgSO4) and concentrated by rotary evaporation. Column chromatography on silica gel (hexane/chloroform=3/1) afforded products as white solids 22DPASF (2.4 g, 60%).
