Effect of solvent on rate of CO2 insertion into (tBuPBP)Pd(CH3) at 40 °C and 1 atm of CO2.
Entry | Solvent | k 1 a (M−1 s−1 × 10−2) | Rate enhancement |
---|---|---|---|
1 | Toluene-d8 | 1.1 | 1 |
2 | Benzene-d6 | 1.3 | 1.2 |
3 | 1,4-Dioxane | 1.5 | 1.4 |
4 | Tetrahydrofuran | 1.8 | 1.6 |
5 | Glyme | 2.1 | 1.9 |
These values are the average of two trials and the errors are ±10%.
