Abstract

A nickel-catalyzed intermolecular three-component 1,1-difunctionalization of unactivated alkenes with quinoxaline/naphthoquinone and arylboronic acids via organometallic-radical relay is developed. This efficient protocol provides a new method to access a variety of arylalkanes in moderate to good yields with a broad substrate scope and excellent functional group tolerance. The mechanistic studies provide insights into the mechanism and origin of chemo- and regioselectivity as well as confirm the generation of functionalized benzylic radicals.
