Reaktionsschritte

Diethyl ethylmalonate (1.88 g, 10 mmol), 1.38 g (10 mmol) of potassium carbonate, 0.1 g of tetra-n-butylammonium chloride hydrate, and 5 mL of carbon tetrachloride were mixed at 70° C. for 3 h. Gas chromatographic analysis of the mixture showed complete conversion of the diethyl ethylmalonate to yield 2.13 g of diethyl α-chloro-α-ethylmalonate (96% yield).
