Copper-Catalyzed Electrophilic Amination of Arylsilanes with Hydroxylamines

A copper-catalyzed electrophilic amination of aryl[(2-hydroxymethyl)phenyl]dimethylsilanes with O-acylated hydroxylamines has been developed to afford the corresponding anilines in good yields. The catalytic reaction proceeds very smoothly under mild conditions and tolerates a wide range of functional groups.
