実験手順
In a 10 mL round-bottom flask, a mixture of 1.46 g dimethyl methylmalonate (10 mmol), 1.69 g tetrachloromethane (11 mmol), 0.27 g potassium carbonate (2 mmol), and 63 mg tetra-n-butylammonium fluoride (0.2 mmol) was mixed by a magnetic stirrer at 24° C. for 5 h. The product mixture was filtered, and gas chromatographic analysis of the filtrate showed the presence of 1.8 g of dimethyl α-chloro-α-methylmalonate (99% yield).
