Figure 4. Mechanistic studies support intermediacy of transient Ni(III) complex to enable C–O reductive elimination.

Figure 4

(a) Reductive elimination to form C–O bond only occurs in the presence of photocatalyst and light. Reactions performed on 5.55 μmol scale with 41 mol% photocatalyst 1 and blue LEDs. See supplementary information for experimental details. (b) Cyclic voltammogram of 45 shows NiIII/NiII couple at +0.83 V vs. SCE in CH3CN with 0.1M tetrabutylammonium hexafluorophosphate as the supporting electrolyte at 100 mVs−1.
