Reaction Steps
Under an argon stream, to a suspension of zinc powder (55.1 g, 843 mmol) in tetrahydrofuran (THF; 56 ml) was added 1,2-dibromoethane (2.9 ml, 33.8 mmol), and the mixture was heated under reflux for 5 min. Subsequently, trimethylsilyl chloride (8.6 ml, 67.5 mmol) was added at 0° C., and the mixture was stirred at 0° C. for 5 min. A solution of 2,3-dichlorobenzyl chloride (82.4 g, 421.7 mmol) in THF (330 ml) was added dropwise under ice-cooling, and after the completion of the dropwise addition, the mixture was allowed to warm to room temperature. The mixture was stirred for 1 hr to give a solution of 2,3-dichlorobenzylzinc chloride in THF.
