实验步骤: 6-Bromophthalide (5.85 gms; 0.0275 mole), N-bromosuccinimide (4.89 gm; 0.0275 mole) and azobisbutyronitrile (0.1 gm) were gently refluxed in dry carbon tetrachloride (200 ml.) for 2 hours. On cooling, the succinimide was filtered off and the solvent removed in vacuo to give an oil, which was used immediately. On cooling the succinimide was filtered off the solvent removed in vacuo to give an oil, which
