Figure 5.

A) The conversion of 1.92 mM tris‐acetal basket 4 in CD₂Cl₂, containing 3.27 M TFA, into 1 was monitored with ¹H NMR spectroscopy (850 MHz, 298 K). A segment of recorded spectra for a period of 338 min is shown. B) The proposed catalytic cycle for the formation of capsularene 1 from tris‐aldehyde basket 2 with the corresponding kinetic parameters and energy minimized structures (OPLS3) of the participating molecules. C) Changes in the concentration of 0.25 mM basket 2, measured for varying initial concentrations of basket 1, were fitted as a function of time to a model of product inhibition to determine the rate coefficient k _app and the dissociation constant K _d2.
