对于R+向π电子系统的加成，观察到比单电子转移（SET）过程计算的速率常数至少大8个数量级。因此，很明显，在这些反应中，通常没有发现自由基中间体，但电荷转移与新的C <$C σ键的形成有关。（图为提交）
Rate constants at least eight orders of magnitude greater than those calculated for the single electron transfer (SET) process are observed for the addition of R+ to π‐electron systems. Thus it is clear that in these reactions radical intermediates are generally not found, but that charge transfer is associated with the formation of the new C C σ bond.(Figure Presented.)
