Versuchsvorschrift

A mixture of 26. 4 grams (0.15 mol) of dimethyl isopropylidenemalonate and 27.5 grams (0.15 mol) of n-bromosuccinimide were stirred in 150 mL carbon tetrachloride containing 1.0 grams benzoyl peroxide. The mixture was refluxed for 16 hours under nitrogen. The reaction was cooled in ice and the succinimide was filtered off and washed with carbon tetrachloride. The solvent was removed under reduced pressure to yield 41.3 grams of impure bromomethyl methyl isopropylidenemalonate as an oil which was used without further purification.
