hexachloromethylenenorbornene is analogous to comparable additions to hexachloro-norbornadiene, and affords 2,3,4,5,5,6-endo-hexachloronorborn-2-en-1-ylmethyl alkyl sulphides as sole products. In contrast, the free-radical addition of bromotrichloromethane and of bromine yields 2-endo-bromo-1,2-exo-3,4,7,7-hexachloro-5-(2,2,2-trichloroethyl)nortricylene and 2-endo-bromo-1,2-exo-3,4,7,7-hexachloro-5- bromomethylnortricyclene
将硫醇添加到六氯亚甲基降冰片烯中类似于添加到六氯降冰片二烯中,并且得到作为单独产物的2,3,4,5,5,6-内-六氯降冰片烯-2-烯-1-基甲基烷基硫化物。相比之下,溴代三氯甲烷和溴的自由基加成产生2-内-溴-1,2-外--3,4,7,7-六氯-5-(2,2,2-三氯乙基)降冰片烯和2 -内-溴-1,2-外--3,4,7,7-六氯-5-溴甲基降三环烯。这些产物的形成是根据各种可能的中间基团来讨论的。
