Metal Bis(acyclic diaminocarbene)-Derived Homochiral Organometallic Frameworks: Synthesis and Asymmetric Catalytic Application.

As an indispensable member of the reticular material family, metal-carbon-based organometallic frameworks (OMFs) remain largely underexplored, and no chiral OMFs (COMFs) have been reported thus far. Herein, we first report the construction of COMFs from a Pd-isocyanide OMF via nucleophilic addition to the Pd-isocyanide moiety with optically pure amines. The obtained Pd-bis(acyclic diaminocarbene) (Pd-BADC)-derived chiral OMFs display excellent applicability and can be reusable chiral catalysts to highly promote asymmetric Strecker and Suzuki-Miyaura cross-coupling reactions in a heterogeneous way.
