Figure 2

Plot of KIE values vs D(C-H) for 1 (filled circles) and 2 (open squares). The filled square represents the KIE value for MeCN as estimated from the t1/2 of 2 in MeCN and MeCN-d3. The shaded area represents KIE values within the semiclassical limit, while the dashed lines highlight the rising and falling trends of the KIEs as a function of C-H bond dissociation energy.
