Rational Design of Porous Organic Framework (POF) for Efficient Conversion of CO 2 to Cyclic Carbonates and 2‐Oxazolidinones at Atmospheric Pressure Conditions

Abstract Carbon dioxide (CO 2 ) capture and its subsequent catalytic fixation into usable compounds represent a potential approach for addressing the energy problem and the implications of global warming. Hence, it is necessary to develop effective catalytic systems required for the transformation of CO 2 into valuable chemicals/fuels. Herein, we rationally designed a hydroxyl‐functionalized porous organic framework (OH‐POF) consisting of both acidic (OH) as well as basic N sites for the transformation of CO 2 using epoxides for the production of cyclic carbonates (CCs), a useful commodity chemical under environmental‐friendly, metal/solvent/co‐catalyst‐free conditions. Moreover, OH‐POF was post‐synthetically modified to anchor non‐noble metal, Zn(II) to generate Zn‐POF and further explored it for the efficient functionalization of CO 2 with propargylic amines to generate valuable bioactive 2‐oxazolidinones. Significantly, both OH‐POF and Zn‐POF demonstrated exceptional reusability with catalytic efficacy retained across numerous cycles of use. Notably, this study showcases a green and sustainable process for utilization of CO 2 under environmentally favorable ambient conditions into two highly valuable compounds, viz cyclic carbonates and 2‐oxazolidinones.
