reactivity of electrochemically generated radical cations toward alcohol and p-toluene sulfonamide nucleophiles was directly investigated through competition experiments. Alcohol-trapping of the radical cation is the kinetically favored pathway and is reversible. Trapping with the sulfonamide leads to the thermodynamic product. Both reaction pathways were investigated computationally with density functional
通过竞争实验直接研究了电化学产生的自由基阳离子对醇和对甲苯磺酰胺亲核试剂的反应性。自由基阳离子的醇捕获是动力学有利的途径并且是可逆的。用磺酰胺捕获导致热力学产物。使用密度泛函理论 (UB3LYP/6-31G(d)) 计算研究了两种反应途径。
