Arylation of indole at C2 catalyzed by palygorskite grafted covalent organic frameworks supported palladium catalyst
Abstract A heterogeneous palladium catalyst, palygorskite grafted covalent organic frameworks supported palladium (Pd-Pal/COF), was successfully prepared by a simple method. A series of C2 aromatic indole derivatives were synthesized under mild reaction conditions. Pd-Pal/COF catalyst can be reused at least 5 times with inappreciable metal leaching. Undoubtedly, facile synthesis, mild reaction conditions, a wide scope of reactants, and recyclability make the catalyst systems potentially useful in organic synthesis. For the synthesized heterogeneous catalysts, palygorskite as a matrix, the unique structure and good dispersion of palygorskite result in the excellent catalytic activity and good cycle stability of the Pd-Pal/COF catalyst, comparing with the traditional clay catalyst. The result further expands the application scope of clay in the catalytic field.
Graphical Abstract Palygorskite grafted covalent organic frameworks supported palladium catalyst was prepared. The catalyst has high catalytic activity for the CH activation of indoles. The catalyst can be easily reused at least 5 times with inappreciable metal leaching. Display Omitted
