| abstract | 559,306. Malonic esters. GAUBERT, P., SMITH, F. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 24, 1942, No. 10355. [Class 2 (iii)] Dialkylphenylmalonates are made by reacting dialkylcarbonates with alkali metal alkoxides in the presence of a hydrocarbon solvent boiling above 100‹ C., the alcohol simultaneously produced being continually removed by distillation. The resulting alkali metal derivatives are decomposed by treatment with dilute mineral acids, or are ethylated, e.g. by means of ethyl halide. In examples: (1) Sodium is melted under toluene, and after solution of the sodium on addition of alcohol, a mixture of diethylcarbonate and ethylphenylacetate is added ; a toluene-ethanol azeotrope is removed and the sodio compound decomposed with dilute hydrochloric acid; finally, diethylphenylmalonate is obtained by distilling the resulting toluene layer ; (2) the sodio compound obtained as in example (1), is reacted with diethylsulphate to give diethylphenylmalonate. |
