Effect of Acidic/Electrophilic Additives on Reductive Elimination from 6

| Entry | Additive | kobs (s−1) | Yield 7[a] |
|---|---|---|---|
| 1 | None | nd[b] | 54% |
| 2 | 10 equiv TFA | 3.31 ± 0.04 × 10−4 | 73% |
| 3 | 10 equiv TFAA | 1.43 ± 0.02 × 10−3 | 84% |
| 4 | 1 equiv Yb(OTf)3 | 2.92 ± 0.03 × 10−4 | 99% |
Conditions: Complex 6 (1 equiv) and the appropriate additive in DCE (0.26 mL) for 12 h at 60 °C. Yields were determined by 19F and 1H NMR spectroscopy and represent an average of at least two independent runs.
kobs could not be determined for this reaction due to an induction period.
