Summary: | The Cu‐glutathione (GSH) redox system, essential in biology, is designed here as a supramacromolecular assembly in which the tetrahedral 18e Cu(I) center loses a thiol ligand upon adsorption onto ZIF‐8, as shown by EXAFS and DFT calculation, to generate a very robust 16e planar trigonal single‐atom Cu(I) catalyst. Synergy between Cu(I) and ZIF‐8, revealed by catalytic experiments and DFT calculation, affords CO2 conversion into high‐value‐added chemicals with a wide scope of substrates by reaction with terminal alkynes or propargyl amines in excellent yields under mild conditions and reuse at least 10 times without significant decrease in catalytic efficiency.
The Cu(I)‐glutathione polymer supported on ZIF‐8 is a robust catalyst for the efficient carboxylation of terminal alkynes and the cyclization of propargylamine with CO2 under atmospheric pressure and mild conditions with a wide range of substrates, converting them into high value‐added chemicals, with strong positive synergy between Cu(I) and ZIF‐8. This catalyst is reused at least 10 times without significant reduction in catalytic efficiency. |
