Aldehyde consumption vs. time in an NMR-monitored Soai reaction (○) (ref. 16) fitted by model 2 (continuous line) and by model 3 (broken line). Initial concentrations (M): [A] = 1.92 × 10–2 and [Z] = 0.04; rate parameters model 2 {model 3}: k0′ = 5.2 × 10–3 {3.7 × 10–3} M–1·s–1; k1′ = 69 M–2·s–1 {k6 = 154 M–2·s–1, k7 = 2.1 × 10–4 M–2·s–1}; k2 = 4.5 × 105 {9.2 × 105} M–1·s–1; k3 = 5.2 × 10–2 {6.4 × 10–4} s–1; k4 = 4.8 × 103 {1.1 × 104} M–1·s–1; and k5 = 21 {6.4 × 10–4} s–1. The first seven data points have not been taken into account.
