%X It is presently well-established
that the synthesis of polycarbonates
or cyclic carbonates from metal-catalyzed reactions of CO2 and oxiranes provides a viable industrial process for the production
of these important chemicals. In this study, we have demonstrated
that CO2 collected under aerobic conditions at atmospheric
pressure over [Cu3(btc)2(H2O)3] (btc = benzene-1,3,5-tricarboxylate) or HKUST-1, a commercially
available metal–organic framework material (MOF), can be utilized
to synthesize poly(propylene carbonate) from propylene oxide and CO2 catalyzed by Co(III) salen catalysts at optimal pressure.
That is, CO2 thermally released from the MOF material selectively
affords copolymer in the pressure range that is not rate-limiting.
Similar results were noted for the copolymerization of the much less
reactive cis-2-butylene oxide monomer with CO2. Comparative studies using CO2 provided directly
from a compressed gas source gave similar results. This investigation
provides a baseline study for the practical use of atmospheric pressure
or below CO2 captured from point sources for the synthesis
of useful chemicals without requiring mechanical compression.
