Activation of a C(sp3)H Bond by a Transient s-Alkylpalladium(II) Complex: Synthesis of Spirooxindoles Through a Palladium-Catalyzed Domino Carbopalladation/C(sp3)C(sp3) Bond-Forming Process
Heck shortens the distance. Palladium-catalyzed activation of C(sp3)-H bond by a σ-alkyl Pd(II) complex generated in situ from a remote arylhalide function is developed. The novel domino carbopalladation/C(sp3)-C(sp3) bond forming process allowed a rapid access to biologically relevant spirooxindoles.
