“…The suppression of the reverse cycloaddition reaction and decreased DMC yield may indicate poisoning of active sites of the catalyst by CO 2 . Previous studies at 5 bar CO 2 have indicted the successful synthesis of DMC from ethylene oxide (Liu et al, 2015).…”

“…Based on the predecessors’ work, the one-pot synthesis process has unlimited development potentials. , CO 2 cycloaddition normally involves ring-opening via nucleophilic attack, CO 2 insertion, and ring closure with the loss of the nucleophile. For example, nucleophiles such as typical halogen anions are used to accelerate the ring-opening, usually the rate-determining step.…”

The multiple-step transformation of CO2 greatly enriches the diversity and value of products and provides more possibilities for the sustainable development of green chemistry. However, it puts forward stricter requirements for the versatility of catalysts. A series of basic porous ionic polymers incorporating azolide anions (BA-PILs) were facilely synthesized via radical polymerization followed by a successive ion-exchange strategy. A one-pot multiple-step integration strategy coupling cycloaddition and transesterification were explored to synthesize chain carbonates without the separation of intermediate products. High catalytic activity, stable recyclability, and chain carbonate compatibility were achieved in the absence of any cocatalyst. Combined with catalysts’ characterization, in situ IR analysis, and density functional theory (DFT) calculation of BA-PILs rationally explained the dual roles of azolide anions in the one-pot synthesis. The construction of functional BA-PILs as a versatile platform provides an original idea for the efficient insertion of CO2 into chain carbonates.

“… 15 High energy consumption and investment occurred by the separation of intermediate products in two-step transesterification. One-pot synthesis of DMC has been proposed as an alternative route, 16,17 but this method is generally accompanied by side reactions. Given the disadvantages mentioned above, the direct synthesis of DMC from methanol and CO 2 is more attractive in terms of green technology, atomic utilization, and cost.…”
