    • reverse for this transformation. The intramolecular nature of [1·2·3] → [3·3] will result in this process being accelerated with respect to the bimolecular pathway 1 + 2 → 3. The reverse process [3·3] → [1·2·3] is still bimolecular, and thus, one would envisage that this rate is close to that for 3 → 1 + 2. The net effect is therefore to increase K for the recognition-mediated process making the formation of 3 from [1·2·3] more favorable.

    • 1H NMR spectroscopy. The disappearance of the resonances arising from the aldehyde protons in 2 and 5 (δ = 9.95-10.05) and the simultaneous appearance of resonances arising from the imine protons in 3 and 6 (δ = 8.42-8.47) were monitored. Concentration vs time profiles were constructed by deconvolution of these resonances.
