Organic synthetic intermediates.
Production Methods
A mixture of diethyl phthalate, carbon tetrachloride, and magnesium was added by drop to a mixture of diethyl malonate, carbon tetrachloride, and ethanol. The reaction was started by heating, and the temperature was controlled to make the reaction gentle. Then add anhydrous diethyl ether, heat for 1h, and add the diethyl ether solution of benzyl chloride (add slowly, not to make the reaction too intense). After the reaction, the oil layer was separated by cooling and adding water, and the diethyl phenyllemalonate was obtained by steaming diethyl ether under reduced pressure.
