反应详情

Zinc (341 mg, 5.22 mmol) was added to a stirred mixture of 6-bromo-1,1,2,2-tetrafluoro-1,2-dihydronaphthalene (730 mg, 2.60 mmol) in tetrahydrofuran and concentrated ammonium hydroxide (4 mL) at 0° C. The mixture was allowed to warm slowly to room temperature. After 6 hours the reaction was diluted with 35 mL of dichloromethane and extracted. The organic layer was washed with water (2×30 mL) dried and concentrated. The residue was purified by chromatography on silica gel eluting with pentane:hexane (1:1) to provide the title compound.
