^aTurnover number (TON), number of equivalents of OX consumed per equivalent of catalyst.
^bRelative integrals, in the normalised ¹H NMR spectrum of CH₂ resonances due OSS versus other heterocarbonate links.
^cDetermined by GPC (gel permeation chromatography) measurements conducted in THF, using narrow MW polystyrene standards to calibrate the instrument.
^dCalculated assuming initiation of both acetate coligands. OX purified over CaH₂ for run #1-#7 and successively over CaH₂ and Na for run #8-#10.
