Versuchsvorschrift

Under an argon atmosphere, a zinc powder (3.18 g) was suspended in tetrahydrofuran (8 ml), 1,2-dibromoethane (0.061 g, 0.32 mmol) and trimethylsilyl chloride (0.071 g, 0.65 mmol) were successively added at 60° C., and the mixture was stirred for 30 min. A solution of 3-chloro-2-fluorobenzylbromide (7.48 g, 32.5 mmol) in tetrahydrofuran (20 ml) was added dropwise at 60° C. to the solution prepared above. The mixture was further stirred under heating for 1 hr to give a solution of 3-chloro-2-fluorobenzylzinc bromide in tetrahydrofuran.
