(2,2'-BIPYRIDINE)DICHLOROPALLADIUM(II)

General procedure: Silver tetrafluoroborate (AgBF4) (0.6 mmol) was dissolvedin methanol (7 mL); (2, 2?-bipyridine) dichloropalladium(II)(Pd(Bpy)Cl2) (0.3 mmol) was dissolved in DMSO (1 mL), and then, the solutions were stirred together at ambient temperature0.5 h. Following gravity filtration, solid 3-hydroxyflavonederivative (0.3 mmol) and triethylamine (0.7 mL)were added to the filtrate. The reaction mixture was stirredfor 0.5 h (2 h for the Fla-OMe). The corresponding bipyridinepalladium flavonolato salt was then recovered usingvacuum filtration and recrystallized in CH3OH/CH3CN solvent;remaining solvent was removed in a vacuum desiccator overnight.General procedure: Silver tetrafluoroborate (AgBF4) (0.6 mmol) was dissolvedin methanol (7 mL); (2, 2?-bipyridine) dichloropalladium(II)(Pd(Bpy)Cl2) (0.3 mmol) was dissolved in DMSO (1 mL), and then, the solutions were stirred together at ambient temperature0.5 h.
