- Isolation of dibromoolefin was accomplished by addition of pentane (4 vol.) to the reaction mixture, filtration to remove insoluble material and evaporation of pentane—methylene chloride. The insoluble fraction was reworked by additional cycles of methylene chloride extraction and pentane precipitation to remove all of the olefinic product. The dibromoolefins II were thus obtained in essentially pure form and could be distilled with very little loss in yield.
