Comparison of the rate constants[a] involving the host–guest complex (kHG) and the piperidinium-catalyzed reaction (kCAT).
| Aldehyde | kHG/kCAT |
|---|---|
| 3 | 3.0 |
| 4 | n.d.[b] |
| 5 | 3.5 |
| 6 | 2.3 |
| 7 | 2.6 |
| 8 | 2.1 |
The reactions are second order and initial rates were used with the same time interval for both rate constant calculations.
Reaction abides by different reaction kinetics and was not compared.
