The free-radical addition of ethanethiol and methanethiol to hexachloronorbornadiene is shown to give as main products, 1,4,5,6,7,7-hexachloronorborn-5-en-2-endo-yl alkyl sulphides and 1,2,3,5-endo,6,6-hexachloro-norborn-2-en-7-syn-yl alkyl sulphides. On oxidation of these sulphides to sulphones epimerisation occurs at C-2 and C-7, respectively. The structure of the Diels–Alder adduct of ethyl vinyl
乙硫醇和甲硫醇在六氯降冰片二烯中的自由基加成显示出主要产物为1,4,5,6,7,7-六氯降冰片烯5-en-2-内基烷基硫化物和1,2,3 ,5-内,6,6-六氯-降冰片烯-2-en-7-顺式烷基硫化物。这些硫化物氧化成砜后,差向异构化分别发生在C-2和C-7处。乙基乙烯基砜和六氯环戊二烯的Diels-Alder加合物的结构被确定为1,4,5,6,7,7-六氯降冰片烯5-en-2-外基-乙基砜。1,2,3,5-内切,6,6-六氯降冰片-2-en-7-顺式烷基硫化物的处理和相应的7-抗等摩尔量的叔丁醇钾的α-砜会导致氯化氢的消除,从而分别生成1,2,3,5,6-五氯降冰片烯2,5-dien-7-基烷基硫醚和砜。
