Reaction Conditions:

with iron(III) chloride in diethyl ether; under 375.038 Torr; for 2.75 h;Reflux;Microwave irradiation;Pressure;Time;

Steps:

4.3

(3) mixing the prepared 2-methyl-4,5-dihydrofuran with diethyl ether into the reaction kettle,The control temperature is 80 ° C, FeCl3 is added, the stirring is uniform, and the control pressure is 0.05Mpa.After microwave treatment for 45 min, the reaction was stirred and refluxed for 2 h.After the reaction is over, add water and mix well.Stirring reaction for 2h, restore the room pressure at room temperature, collect the organic layer,Vacuum distillation,5-Chloro-2-pentanone was obtained.
