  • Title: Copper and Palladium Cocatalyzed Defluorinative Coupling of gem-Difluoroalkenes and Acyl Chloride.
    Author: Liu X, Wu J, Zhang C.
    Journal: Org Lett; 2023 Mar 10; 25(9):1564-1568. PubMed ID: 36852955.
    Abstract:
    A novel copper and palladium cocatalyzed defluorinative coupling of gem-difluoroalkenes and acyl chlorides has been developed. It is a practical method to prepare α-fluorochalcones, which are a kind of important unit in a variety of bioactive compounds. Under mild reaction conditions, a series of substrates with various functional groups could afford desired products smoothly. Further synthetic studies illustrated that the products of this chemistry could be used as versatile precursors to access complicated compounds. Furthermore, the reaction mechanism was proposed based on control experiments.
