10 g (41.6 mmol) 4-dibenzothiophene boronic acid, 6.25 g (39.6 mmol) bromobenzene, 366 mg (0.39 mmol) Pd2(dba)3, 656 mg (1.6 mmol) S-phose, 25.4 g (120 mmol) K3PO4, 180 mL toluene and 20 mL water were charged in a 500 mL flask. The mixture was heated up to reflux under nitrogen for overnight. The reaction mixture was purified by silica gel column chromatography with pure hexane as elute. ˜8.5 g (83%) white solid was obtained as product which was confirmed by MS.
