Figure 2.

A) Plot of the logarithm of the second order rate constants k ₂′ (normalized to the number of equivalent H atoms) of the reactions of 2 with different substrates vs. the BDE_C‐H of the respective substrates; the inset shows the substrates that deviate from a linear correlation; B) Plot of the logarithm of the second order rate constants k ₂ of the reactions of 2 with different polycyclic substrates vs. the ionization energy of the respective substrates; C) plot of the first‐order rate constants k _obs vs. the concentration of ethylbenzene (black) and d ₁₀‐ethylbenzene (grey) for determination of the second‐order rate constants k ₂ and the deuterium KIE; D) plot of the first‐order rate constants k _obs vs. the concentration of DHA (black) and d ₄‐DHA (grey) for determination of the second‐order rate constant k ₂ and the deuterium KIE.
