Extended Data Figure 10: NMR spectra for the Cs2CO3 recycling experiment.
From: Carbon dioxide utilization via carbonate-promoted C–H carboxylation
a, 1H NMR (400 MHz) in CDCl3 of the DMFD isolated after the second carboxylation/esterification sequence. b, 1H NMR (400 MHz) in D2O of the material recovered from the aqueous phase after the second carboxylation/esterification sequence.
