Entries 1-3 in Table , corresponding to H2O concentrations of 0, 1, and 2 M, are in good agreement with the CV data presented in Figures , S10, and S11, where high conversion yields (CPE) are predicted by a significant decrease in the voltammetric ipa in the presence of 4-BrBN (CV). Then, entry 5 in Table agrees with the CV study shown in Figure , where the low conversion yield in the presence of 8 M H2O, 5%, correlates to ipa being unchanged upon addition of 4-BrBN, Figures and.
