実験手順
An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with palladium acetate (2.2 mg, 0.01 mmol, 1.0 mol %), 2-(di-tert-butylphosphino)biphenyl (4.5 mg, 0.015 mmol, 1.5 mol %), phenylboron dihydroxide (183 mg, 1.5 mmol), additive (3.0 mmol), and 4-chlorotoluene (0.12 mL, 1.0 mmol). The tube was evacuated and backfilled with argon, and THF (2 mL) was added through a rubber septum. The reaction mixture was stirred at room temperature for 20 hours. The reaction mixture was then diluted with ethyl acetate (30 mL) and poured into a separatory funnel. The mixture was washed with 2.0M NaOH (20 mL), followed by brine (20 mL). The organic layer was submitted for GC analysis giving the results tabulated below.
