The addition of bromine in carbon tetrachloride or acetic acid to hexachloronorbornadiene affords the products of endo-cis- and trans-addition of bromine to the unsubstituted double bond, and the rearrangement product 5-exo,-7-anti-dibromo-1,2,3,5-endo,6,6-hexachloronorborn-2-ene. With chlorine, in addition to the products of endo-cis- and trans-addition, two rearrangement products, 1,2,3,5,5,6,6,
在四氯化碳或乙酸中将溴添加到六氯降冰片二烯中,得到内-顺-和反式加成溴到未取代的双键的产物,以及重排产物5- exo,-7-抗-dibromo-1,2 ,3,5-内酯,6,6-六氯降冰片-2-烯。与氯,除了对产品内-顺-和反式-addition两个产物,1,2,3,5,5,6,6,7-抗-octachloronorborn -2-烯及其7- SYN-epimer,形成。已经研究了温度变化以及添加的自由基催化剂和抑制剂对产物比率的影响,从而为这些加成反应中可能的中间体提供了证据。硫酰氯已用于以自由基方式向六氯降冰片二烯中添加氯元素。这提供了未取代的双键的内-顺-和反-加成产物以及抗-八氯降冰片-2-烯的重排产物1,2,3,5,5,6,6,7- 。
