실험 절차
A solution of 3.25 g tetrabromomethane (10 mmol), 1.46 g dimethyl methylmalonate (10 mmol), and 100 mg tetra-n-butylammonium fluoride trihydrate (0.316 mmol) in 5 mL tetrahydrofuran (THF) was stirred for 10 min at 24° C. Gas chromatographic analysis of the resulting mixture showed that it contained 87% yield of both dimethyl α-bromo-α-methylmalonate (1.97 g) and bromoform (2.2 g).
