Reaction conditions: 1 (3 mM), PO (6 mL), 1,2-cyclohexane diol (60 mM), 70 °C, 1.4 h.

Data supplied by ref (32).

PO conversion determined from the relative integrals in the ¹H NMR spectrum of the resonances assigned to PPC (4.92 ppm, 1H), PC (4.77 ppm, 1H), and PPO (3.46–3.64 ppm, 3H) against mesitylene (6.70 ppm).

CO₂ uptake (%) determined by the relative integrals in the ¹H NMR spectrum of the resonances assigned to (PPC + PC)/PPO.

Polym selectivity (%) determined by the relative integrals in the ¹H NMR spectrum of the resonances assigned to PPC/(PC + PPC).

Turn-over frequency (TOF) = TON/time (h).
