A nickel-catalyzed domino Heck cyclization/Suzuki coupling reaction enables the synthesis of 3,3-disubstituted oxindoles bearing quaternary all-carbon centers. A wide range of electrophiles, such as aryl iodides, bromides, triflates, chlorides, and cheap aryl esters can be employed. This practical and sustainable reaction offers good yields and broad scope.
