Three reaction paths, namely, molecule‐induced homolytic, free radical, and electrophilic, were modeled computationally at the MP2 level of ab initio theory and studied experimentally for the reaction of F2 with the terminal dienes of bicyclo[3.3.1]nonane series. The addition of fluorine is accompanied by transannular cyclization to the adamantane derivatives in which strong evidence for the electrophilic
从头计算理论在MP2水平上对分子诱导的均裂,自由基和亲电的三个反应路径进行了建模,并对F 2与双环[3.3.1]壬烷系列的末端二烯的反应进行了实验研究。。氟的添加伴随着环向金刚烷衍生物的环过环化,其中发现了在亲核(乙腈)和非亲核(CFCl 3,CHCl 3)溶剂中都有亲电机理的有力证据。CFCl 3和CHCl 3中存在KF有助于添加,并大大减少了焦油产物的形成。
