Abstract

A general aminoalkylation of aryl halides was developed, overcoming intolerance of free amines in nickel-mediated C-C coupling. This transformation features broad functional group tolerance and high efficiency. Taking advantage of the fast desilylation of α-silylamines upon single-electron transfer (SET) facilitated by carbonate, α-amino radicals are generated regioselectively, which then engage in nickel-mediated C-C coupling. The reaction displays high chemoselectivity for C-C over C-N bond formation. Highly functionalized pharmacophores and peptides are also amenable.
