Experimental conditions shared by all experiments: H2O, 1 M Tris-buffer pH 7.7, at 25 °C; other parameters are indicated for specific experiments. a. Experimental data showing sustained oscillations in the system with catalyst 2. [8] = 64 mM; [9] = 114 mM; [1] = 83.2 mM; [2] = 0.14 mM; f/V = 1.46·10−3 s−1. b. Experimental data showing sustained oscillations in the system with catalyst 3. [8] = 56 mM; [9] = 100 mM; [1] = 72.8 mM; [3] = 0.5 mM; f/V = 1.67·10−3 s−1 c. Experimental data showing sustained oscillations in the system with catalyst 4. [8] = 56 mM; [9] = 100 mM; [1] = 72.8 mM; [4] = 1 mM; f/V = 1.67·10−3 s−1 d. Experimental data showing sustained oscillations in the system with catalyst 5. [8] = 56 mM; [9] = 100 mM; [1] = 72.8 mM; [5] = 2 mM; f/V = 1.67.10−3 s−1. RSH stands for the sum of the concentrations of all three thiols in the system. Chemical structures of catalysts 2-4 are shown above corresponding plots.
