^aReactions were run using a catalyst : CHO molar ratio of 1 : 1000 at 80 °C under 1 bar pressure of CO₂ for 6 hours.

^bSee Table 1 and ESI for all data (Fig. S61–S64).

^cCHD = 1,2-cyclohexanediol.

^dCatalyst and CHO were stirred in air for 1 h at 25 °C before purging the system with CO₂ and heating to 80 °C.
