Abstract

Abstract: Covalent organic frameworks (COFs), also called "Organic Zeolites, " are crystalline porous organic polymers with robust and pre‐designable architecture and high crystallinity. They can be structurally controlled and functionally managed, due to the availability of diverse organic functionalities, covalent linkages and topologies. The current review briefly outlines their design strategies and comprehensively discusses their applications in the carbon‐carbon bond formation reactions. The reactivity of COF‐based catalysts with their homogeneous counterparts, catalyst stability, role of matrix, tailored organocatalysts and substituent effect on the reaction parameters, chemo‐/stereo‐/regioselectivity, shape/size selectivity are also discussed. Finally, the challenges and future prospects of functionalized COF‐based catalysts are discussed. These discussions will provide a better understanding of the role of COF‐based catalysts in the C−C bond formation and will also open doors to the design and synthesis of more robust, sustainable and benign catalytic systems, which might play a key role in organic synthesis and catalysis. Abstract : The COFs permit incorporation of organic moieties, metal ions, metal complexes, NPs and ligands into the catalyst frameworks with tuneable topology, chemistry, and function. The appended catalytic groups infuse higher shape, size and stereoselectivity, recyclability, excellent yields and shorter reaction time. COFs offer superior catalytic ability as compared to several heterogeneous/ homogeneous catalysts. The current paper describes applications of COF based catalysts in C−C bond forming reactions.
