Abstract
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. We anticipate that this type of chiral reticular material will be applicable to a broad range of asymmetric catalytic applications, and this appealing synthetic strategy will likely provide access to more other such materials with unprecedented structures and catalytic activities.
