Application	diethyl allyl malonate is an organic intermediate obtained by reacting diethyl malonate with allyl bromide. It has been reported that it can be used to prepare an insecticide for Anopheles sinensis.
preparation	under a nitrogen atmosphere, add diethyl malonate (20g) to a 500 mL three-necked round bottom flask, anhydrous potassium carbonate (43g) and anhydrous CH3CN(200). The reaction mixture was stirred at room temperature for 10 minutes and then allyl bromide (23g) was slowly added to the reaction mixture at room temperature. The reaction mixture was heated to 80 °c for 24 hours. The reaction mixture was cooled to room temperature and filtered through a Celite bed. The Celite bed was washed with acetonitrile (100ml) and the combined filtrates were concentrated to give diethyl allylmalonate (24g) as a colorless liquid.
Use	use as raw material and pesticide intermediate in medicine use as raw material and pesticide intermediate in medicine.
