Its CAS number is 20320-59-6, its molecular formula and molecular weight are C 15 H 18 O 5 and 278.30000, and its mass is 278.11500

Diethyl(phenylacetyl)malonate  another name is Phenylacetylmalonic acid ethylester  Its CAS number is   20320-59-6

The main use is organic synthesis intermediates. Production method Add diethyl phthalate and metal sodium co-distilled absolute ethanol dropwise to the mixture of diethyl malonate, carbon tetrachloride and magnesium, heat to start the reaction, control the temperature to make the reaction gentle Chemicalbook. Then add anhydrous ether, heat for 1h, add the ether solution of phenylacetyl chloride (slowly added, not to make the reaction too intense). After the reaction is complete, cool and add water, separate the oil layer, distill off ether under reduced pressure to obtain diethyl phenylacetylmalonate.
