【摘要】 对于自由基分子加成反应，提出了利用不饱和烃的第一电离势与自由基基团的电子亲合能同反应速率常数（取对数形式）进行并联的估算方法；此外，根据前线轨道理论的基本假设，采用不饱和烃分子的最高占据轨道能量及自由基基团的最低空轨道能量同反应速率常数（取对数形式）进行关联，同样取得了令人满意的估算结果更多还原

【Abstract】 In this paper, the reactivity of radical molecular addition reaction has been studied by two method, i.e., lg k =3.08-0.43× Ix -4.3× Ax and lg k =4.155+0.217×E HOMO -2.17×E HUMO where Ix and E HOMO represent the ionization potential and the highest occupied orbit energy of unsaturated organic compounds, Ax and E HUMO represent the electron affinities energy and the lowest empty orbit energy of radical. Thus, the rate constants of radical molecular addition reactions can be estimated by two methods above.更多还原
