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 CC σ bond.
