5-溴-1,1,1-三氟-4-甲氧基戊-3-烯-2-one

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

实验步骤: 24.8 g (0.1 mol) of 5-bromo-1,1,1-trifluoro-4-methoxypent-3-en-2-one, 20 g of potassium acetate, 5 g of tetrabutylammonium bromide and 8 g of acetic acid were stirred in 300 ml of acetonitrile at 40° C. for 20 h. The precipitate was filtered off and the solvent was removed completely under reduced pressure. The precipitate was filtered off the solvent was removed completely under reduced pressure
