Figure 4.5. (left) The comparison of LSVs for 0.5 mol% DiPh-NTf2 (olive) and DiMeOPh-NTf2 (blue) for CO2 reduction in anhydrous acetonitrile. (right) Electron density map (from VDD charge analysis) which shows DiPh as more electron poor, thus a more acidic cation. Figure 4.6. (left) The comparison of LSVs for 0.5 mol% MM-NTf2 (red) and DiPh-NTf2 (olive) for CO2 reduction in anhydrous acetonitrile. (right) Electron density map (from VDD charge analysis) which shows that DiPh is slightly more electron poor. Stability of DiPh-NTf2 after electrolysis was confirmed with NMR analysis (see Supporting Information Figures S4.1-S4.3)
