Heck shortens the distance: A method for the palladium-catalyzed activation of a C(sp3)[BOND]H bond by a σ-alkyl PdII complex generated in situ from a remote arylhalide function has been developed. This approach allows a novel domino carbopalladation/C(sp3)[BOND]C(sp3) bond-forming process to provide rapid access to biologically relevant spirooxindoles.
