The free-radical addition of hydrogen bromide to hexachloromethylenenorbornene affords a 60 : 40 mixture of 1-bromomethyl-2,3,4,5,5,6-endo-hexachloronorborn-2-ene and 5-endo-bromomethyl-1,2,3,4,7,7-hexachloronorborn-2-ene. The aluminium bromide-catalysed ionic addition gives a 68 : 32 mixture of 5-exo-bromo-1,2,3,4,7,7-hexachloro-5-endo-methylnorborn-2-ene and its 5-endo-bromo-epimer.
自由基加成的溴化氢,以hexachloromethylenenorbornene的一个得到60:1-溴甲基- 2,3,4,5,5,6- 40混合物内-hexachloronorborn -2-烯和5-内切溴甲基-1,2- ,3,4,7,7-六氯降冰片-2-烯。溴化铝催化的离子加成反应产生5-外-溴-1,2,3,4,7,7-六氯-5-内甲基甲基降冰片烯2-烯及其5-内溴的68:32混合物-epimer。
