A comparison of computed transition structure energies for intramolecular hydrogen abstraction reactions of cyclodecanone triplet state at gamma vs epsilon carbonhydrogen bonds leads to the prediction that abstraction of γ-hydrogen atoms should be more facile than abstraction of ε-hydrogen atoms. Irradiations in cyclohexane are reported to produce only 10-decalols, products of ε-hydrogen atom abstraction
比较环癸烷酮三重态在γ与ε碳氢键之间的分子内氢抽象反应的计算的跃迁结构能,可以得出这样的预测:γ-氢原子的提取比ε-氢原子的提取更容易。据报道在环己烷中的辐射仅产生10-癸醇,是ε-氢原子提取的产物。经叔丁醇辐照,生成的1-羟基双环[6.2.0]辛烷为主要产物,与计算结果相符。根据竞争性可逆氢提取步骤对结果进行了合理化。
