Thiols react with 5-substituted norborn-2-ene derivatives to afford 2-exo- and 3-exo-sulphides by addition across the double bond. Product proportions appear to depend on the relative stability of the intermediate radicals formed by attack at positions 2 and 3 respectively, and, in additions of benzenethiol, also on the variation in the degree of reversibility of radical attack at positions 2 and 3
硫醇与5-取代的降冰片烯-2-烯衍生物反应,通过跨双键加成而提供2- exo-和3- exo-硫化物。产物的比例似乎取决于分别在位置2和3处进攻形成的中间自由基的相对稳定性,以及苯硫醇的添加,还取决于在位置2和3处自由基进攻的可逆性变化。硫醇与Norborn-2-en-5-one形成2- exo-,3- exo-和7-抗硫化物,最后一个起源于在位置2处由自由基进攻形成的中间体的重排或通过攻击第2位形成非经典的均烯化自由基。
