反応手順
In a 10 mL round-bottom flask, 1.88 g of diethyl ethylmalonate (10 mmol), 2.10 g of ethyl trichloroacetate (11 mmol), 158 mg of tetra-n-butylammonium fluoride trihydrate (0.5 mmol), and 69 mg of potassium carbonate (0.5 mmol) were stirred at 24° C. for 5 h. After filtration, the solution was found to contain 1.56 g (70% yield) of diethyl α-chloro-α-ethylmalonate.
