1-Bromo-4-chloro-2,3-difluorobenzene

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 1-bromo-4-chloro-2,3-difluorobenzene (720 mg, 3.17 mmol) in tetrahydrofuran (10 mL) was added i-propylmagnesiumchloride (1.90 mL, 3.80 mmol) at 0° C. The reaction mixture was stirred at 0° C. for 1 h. Then 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxa-borolane (0.98 mL, 4.75 mmol) in tetrahydrofuran (5.0 mL) was added. The reaction mixture was allowed to warm up to room temperature and stirred at RT for 1 h. The mixture was used directly in the next step. to warm up to room temperature stirred at RT for 1 h
