Figure 2. Component exchange within the multi-component assembly.

Figure 2

a, Exchange of IPA derived assembly 4 (bottom panel) with 3-methyl-2-butanol (middle panel) and with 3,3-dimethyl-2-butanol (top panel). Only the methine portion of the 1H NMR spectra is shown. b, The structures of the alcohols and their respective equilibrium constants for exchange. Keq = [4(R2OH)][R1OH]/{[4(R1OH)][R2OH]}. c, Exchange of thiazole-2-carboxaldehyde derived assembly (bottom panel) with 2-PA (top panel). Resonance from thiazole-2-carboxaldehyde at 10 ppm increased. d, The structures of the aldehydes and their respective equilibrium constants for exchange. Keq = [4(A2)][A1]/{[4(A1)][A2]}. X is the counterion for zinc (chloride or triflate).
