Summary of the specified ligand loss rates from 3 as a function of pyridine concentration in CD2Cl2. Data confirms pyridine loss is dissociative and that both hydride site interchange and H2 loss occurs after this step.
| No. of py eq. by NMR ratio | Rate of py loss / s −1 | Rate of H2 loss / s −1 |
|---|---|---|
| 15 | 0.28 ± 0.03 | 0.078 ± 0.003 |
| 25 | 0.28 ± 0.03 | 0.071 ± 0.003 |
| 30 | 0.31 ± 0.01 | 0.053 ± 0.002 |
| 50 | 0.28 ± 0.03 | 0.042 ± 0.002 |
