7-hexachloronorborna-2,5-dien-5-ylmethyl bromide, its allylic rearrangement product 6-endo-bromo-1,2,3,4,7,7-hexachloro-5-methylenenorborn-2-ene, and 5-bromomethylene-1,2,3,4,7,7-hexachloronorborn-2-ene. The last compound has its origin in the Diels–Alder addition of hexachlorocyclopentadiene to bromoallene, which is produced in the thermal isomerisation of prop-2-ynyl bromide under the reaction conditions
六氯环戊二烯与丙-2-炔基溴之间的反应提供了Diels–Alder加合物1,2,3,4,7,7-hexachloronorborna-2,5-dien-5-ylmethyl bromide,其烯丙基重排产物6-内-溴-1,2,3,4,7,7-六氯-5-亚甲基降冰片-2-烯和5-溴亚甲基-1,2,3,4,7,7-六氯降冰片-2-烯。最后一种化合物的起源是在对丙-2-炔基溴化物在反应条件下进行热异构化过程中,将六氯环戊二烯与溴代丙二烯进行了狄尔斯-阿尔德反应。1,2,3,4-四氯环戊二烯和1,2,3,4,5-五氯环戊二烯与丙-2-炔基溴的反应生成可比的产物。氯环戊二烯在纯溴丙二烯中的Diels-Alder加成反应只得到5-溴代亚甲基化合物,除了微量的6-内-溴-1,2,3,4,7,7-六氯-5-甲基-烯基降冰片烯-烯,是由六氯环戊二烯和溴丙二烯形成的另一种次要产物。
