  • Title: In situ activation of COOH-functionalized ZIF-90-enabled reductive CO2N-formylation.
    Author: Zhu K, Li Y, Li Z, Liu Y, Wu H, Li H.
    Journal: Chem Commun (Camb); 2022 Nov 15; 58(91):12712-12715. PubMed ID: 36310504.
    Abstract:
    A heterogeneous ZIF-90-based catalyst functionalized with COOH and with a porous structure was facilely prepared for efficient CO2 adsorption and activation to undergo reductive N-formylation with a wide range of amines (15 examples) to furnish N-formamides (78-94% yields). The -COO- species generated by an in situ interaction with amine acts as a key species for activating hydrosilane to capture CO2, and remarkably facilitates a cascade C-N coupling and hydrogenation process. Our findings show a facile strategy for the rational construction of robust active sites for reductive CO2 valorization.
