Copolymerizations run in neat cyclohexene oxide (CHO) with [Co]/[[PPN]Cl] = 1:1 at 1.5 MPa of CO2 in 1,4-dioxane (7 ml)

aBased on isolated poly(cyclohexene carbonate) yield

bTurnover frequency: mol CHO mol Co−1 h−1

cDetermined by 1H NMR spectroscopy (CDCl3, 300 MHz)

dDetermined by gel permeation chromatography calibrated with polystyrene standards in tetrahydrofuran at 40 °C
