Nickel-Catalyzed Dicarbofunctionalization of Alkenes

As a straightforward strategy for rapidly increasing molecular complexity,dicarbofunctionalization of alkenes has attracted substantial interests of organic synthesis,medicine chemistry,and materials science.Nickel-catalyzed cascade dicarbofunctionalizations have been flourished in this area recently,and nickel-mediated radical pathways particularly offer new opportunities in conjunctive cross-couplings with alkyl coupling partners.Herein,we give a comprehensive review of nickel-catalyzed dicarbofunctionalization of alkenes through a historical perspective,including intermolecular three-component reactions and intramolecular cascade reactions.Among the pathways discussed in this review,the carbometallation/cross-coupling process and the radical addition/cross-coupling process are the two major pathways for the nickel-catalyzed dicarbofunctionalization of alkenes.The oxidative cyclization and 1,2-metallate shift processes are also selectively discussed.These methods overcome the limitations associated with the reactions using noble metals in the field,providing an efficient and straightforward access to structurally diversified molecules.
