An efficient method for the copper-catalyzed N-arylation of hydroxylamines with aryl iodides allows the conversion of various N- and O-functionalized hydroxylamines in good to excellent yield with a broad range of aryl coupling partners. Methods for the selective deprotection of either the N- or O-substituents for further functionalization are also described.
