176 mg (90%) palladium diacetate; In tetrahydrofuran; nitrogen; toluene; EXAMPLE 45 Synthesis of 4-acetylbiphenyl from an aryl bromoide utilizing 0.000001 mol percent Pd An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with phenylboronic acid (228 mg, 1.5 mmol), and potassium phosphate (425 mg, 2.0 mmol), and 4-bromoacetophenone (199 mg, 1.0 mmol). The tube was evacuated and backfilled with argon, and toluene (1.5 mL) was added through a rubber septum. In a separate flask in a nitrogen filled glovebox, palladium acetate (4.5 mg, 0.02 mmol) and 2-(di-tert-butylphosphino)biphenyl (12.0 mg, 0.04 mmol) were dissolved in 20 ml, THF under argon. A portion of this solution (10 muL, 0.00001 mmol Pd, 0.001 mol percent Pd) was added to a second flask contaninig 10 mL THF). A portion of this second solution (10 muL, 0.00000001 mmol Pd, 0.000001 mol percent Pd) was added to the reaction mixture, followed by additional toluene (1.5 mL) through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was heated to 100° C. with stirring until the starting aryl bromide had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL) and poured into a separatory funnel. The mixture was washed with water (20 mL), and the aqueous layer was extracted with ether (20 mL). The combined organic layers were washed with brine (20 mL), dried over anhydrous magnesium sulfate, filtered, and concentrated. The crude material was purified by flash chromatography on silica gel to afford 176 mg (90percent) of the title compound.

The tube was evacuated and backfilled with argon, and toluene (1.5 mL) and 4-chloroacetophenone (0.13 mL, 1.0 mmol) were added through a rubber septum.
