The cobalt(II) chloride-catalysed reaction of methylmagnesium iodide with 5-endo-bromo-1,2,3,4,7,7-hexachloronorborn-2-ene affords 5-endo-bromo-1,2,3,4,7-syn-pentachloronorborn-2-ene, 5-endo-bromo-1,2,3,4,7-anti-pentachloronorborn-2-ene, 1,2,3,5-endo, 6-endo-pentachloronorborn-2-ene, 1,2,3,5,6-pentachloronorborna-2,5-diene, 1,2,3,5-tetrachloronorborna-2,5-diene, and 1,2,3-trichloro-5-methylnorborna-2
钴(II)与5-甲基碘化镁的氯化物催化反应内溴1,2,3,4,7,7-hexachloronorborn -2-烯,得到5-内切溴-1,2,3,4- ,7-顺-pentachloronorborn -2-烯,5-内切溴1,2,3,4,7-抗-pentachloronorborn -2-烯,1,2,3,5-内,6-内切-pentachloronorborn -2-烯,1,2,3,5,6-五氯降冰片-2,5-二烯,1,2,3,5-四氯降冰片-2,5-二烯和1,2,3-三氯-5-甲基降冰片-2,5-二烯以及痕量的1,2,3,5-内含物,6-外-五氯降冰片-2-烯和1,2,3,5-内含物-四氯降冰片-2-烯。就通过从5-卤代内溴和桥氯原子的起始卤化物中除去所产生的自由基的中间体形成而言,产物的形成可以在很大程度上合理化。5-内-溴-1,2,3,4,7-顺-五氯诺邦-2-烯的反应,5-外-溴-1,2
