Table 1. Experiments Used To Train the Kinetic Modela.
entry | Ni(cod)2 content (mol %) | temperature (°C) | concentration (M) | maximum conversionb (%) | time (h) |
---|---|---|---|---|---|
1 | 10.0 | 40 | 0.66 | 92 | 8 |
2 | 10.0 | 33 | 0.66 | 70 | 6 |
3 | 10.0 | 50 | 0.66 | 91 | 4 |
4 | 0.5 | 65 | 1.16 | 77 | 8 |
5 | 0.1 | 80 | 1.16 | 13 | 1 |
All reactions were performed on a 0.50–1.00 mmol scale, with respect to amide 1, using 1.2 equiv (−)-menthol (2) and a 1:1 ratio of Ni(cod)2:SIPr in toluene.10
Conversion was determined by SFC analysis, using biphenyl as an internal standard.
