Au-Acyclic Diaminocarbene-Linked Homochiral Covalent Organic Frameworks: Synthesis and Asymmetric Catalytic Application

Chiral covalent organic framework (CCOF)-based heterogeneous catalysts are the new hot topic in asymmetric catalysis. The chiral metal-acyclic diaminocarbene complexes (M-ADCs), on the other hand, make up a powerful class of homogeneous catalysts for various asymmetric organic transformations. The integration of chiral M-ADCs with COFs into a single platform will undoubtedly lead to a new breed of heterogeneous asymmetric catalysts. Here, we report the synthesis of Au-ADC-linked CCOFs via a metal-mediated nucleophilic addition approach. This research not only provides a new type of COF linkage but also affords a new kind of heterogeneous catalysts for asymmetric catalysis.
