Cu x O y Incorporated COF: A Potential Reusable Catalyst for the Synthesis of α‐Hydroxy Ketones and Oxazolidinones Under Atmospheric CO 2 Pressure and Solvent‐Free Conditions

In this present work, a newly designed metal‐oxide nanoparticle incorporated Covalent organic framework (COF), Cu x O y @TFP‐ODA has been successfully synthesized and used for the effective synthesis of Oxazolidinones and a‐hydroxy ketones under mild conditions utilizing CO 2 . Initially, imine‐linked 2D COF, TFP‐ODA was synthesized by simple solvothermal method followed by the embedment of copper oxide nanoparticles (NPs) into the skeleton of the as‐synthesized COF. Different characterization techniques were employed to establish the physical and chemical characteristics of both Cu x O y @TFP‐ODA and TFP‐ODA COF materials. To study the catalytic efficiency of the highly porous Cu x O y @TFP‐ODA, three components coupling reaction involving primary amine, propargyl alcohol and CO 2 to synthesize a series of 2‐Oxazolidinone and synthesis of α‐hydroxy ketones using CO 2 as a Co‐catalyst were carried out over the as‐prepared catalyst under green and sustainable conditions which illustrated excellent yields and selectivity of the corresponding products. The synthesized catalyst was proved to be completely heterogeneous and especially, the catalyst material demonstrated significant potential for reuse across several catalytic cycles.
