실험 절차

A mixture of benzoquinone, 10.8 g. toluene (40 ml) and 1,2,3,4,5,5-hexabromo-1,3-cyclopentadiene (60 g.) was heated to reflux temperature and refluxed for four hours. At the end of this reaction period a dark solid had formed. This solid was placed on a Buchner funnel and washed with Skelly B solvent and a small amount of methanol. The solid was then recrystallized from benzene and white crystals were obtained, m.p. 204°-206° C.
