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%
[a]

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.

[b]

kobs could not be determined for this reaction due to an induction period.
