We report a three-component olefin reductive dicarbofunctionalization for constructing densely functionalized alkylborates, specifically, nickel-catalyzed reductive dialkylation and alkylarylation of vinyl boronates with a variety of alkyl bromides and aryl iodides. This reaction exhibits good coupling efficiency and excellent functional group compatibility, providing convenient access to the late-stage modification of complex natural products and drug molecules. Combined with versatile alkylborate transformations, this reaction could also find applications in the modular and convergent synthesis of complex, densely functionalized compounds.
