Abstract
- The utilization of CO<subscript>2</subscript> from flue gas as a C1 feedstock for the catalytic synthesis of high-valued oxazolidinones is highly important but challenging due to the low CO<subscript>2</subscript> concentration and high activation barrier for CO<subscript>2</subscript>. Herein, we present an efficient and stable Cu<superscript>I</superscript>-anchored porous covalent organic framework Cu<superscript>I</superscript>@TpBD-COF for effective catalysis of the carboxylic cyclization reaction between propargylic amines and CO<subscript>2</subscript> to produce various functionalized oxazolidinone derivatives under mild conditions. The yield is up to 99% and the turnover frequency (TOF) reaches a record value of 1058 h<superscript>−1</superscript>, significantly surpassing almost all previously reported metal heterogeneous catalysts. Furthermore, Cu<superscript>I</superscript>@TpBD-COF also demonstrates efficient catalytic activity when simulated flue gas is used as the source of CO<subscript>2</subscript>. This work provides new guidance for the design of more efficient and eco-friendly noble-metal-free catalytic materials to drive the ideal CO<subscript>2</subscript> chemical fixation process.
