6-氯己-1-烯-3-one

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 6-chlorohex-1-en-3-one (from step 3) in isopropanol (80% solution in water, 30 mL) at 0° C. were added potassium bromide (4.8 g, 40 mmol) and bromine (2.0 mL, 39 mmol). After 1 hour, the reaction mixture was quenched with water (15 mL) and extracted with ethyl acetate (3×30 mL). The organic layers were combined, dried over magnesium sulfate, filtered, and concentrated under reduced pressure to afford 1,2-dibromo-6-chlorohexan-3-one, which was used without further purification. the reaction mixture was quenched with water (15 mL) extracted with ethyl acetate (3×30 mL) dried over magnesium sulfate filtered concentrated under reduced pressure
