An efficient method for the copper-catalyzed N-arylation of hydroxylamines with aryliodides is described. A variety of N- and O-functionalized hydroxylamines were transformed in good to excellent yield with a broad range of arylcoupling partners. Methods for the selective deprotection of either the N- or O-substituents for further functionalization are also described.

The bis-pyrazole phosphine ligand BippyPhos is effective for the palladium-catalyzedcross-coupling of hydroxylamines with arylbromides, chlorides, and iodides. Reactions proceed smoothly at 80 °C in toluene in the presence of Cs2CO3 to give synthetically versatile N-arylhydroxylamine products in good to excellent yield.
双吡唑膦配体BippyPhos对于钯催化的羟胺与芳基溴化物,氯化物和碘化物的交叉偶联有效。在80 C的甲苯中,Cs 2 CO 3的存在下,反应平稳进行,从而以良好至极佳的收率获得了合成用途广泛的N-芳基羟胺产品。
