Versuchsvorschrift

In a 10 mL round-bottom flask, a mixture of 1.46 g dimethyl methylmalonate (10 mmol), 1.69 g tetrachloromethane (11 mmol), and 63 mg tetra-n-butylammonium fluoride (0.2 mmol) was mixed by a magnetic stirrer for 15 min at 24° C. Gas chromatographic analysis of the product mixture showed that the solution contained 1.14 g of dimethyl α-chloro-α-methylmalonate (63% yield).
