The invention concerns a method for preparing alkoxyamines in a biphasic medium. Said method consists in mixing an ionic liquid, an organic solvent, a metal salt, a metal ligand, a halogeno-carbonaceous ZX compound and a nitroxide, maintaining the reaction medium under agitation at a temperature between 20° C. and 90° C., until the nitroxide is eliminated, decanting, recuperating the organic phase, optionally washing it with water and then in isolating the alkoxyamine by evaporating the organic solvent under reduced pressure.
该发明涉及一种在两相介质中制备烷氧胺的方法。该方法包括混合离子液体、有机溶剂、金属盐、金属配体、卤代碳氢ZX化合物和亚硝基,在20°C至90°C的温度下将反应介质保持在搅拌状态,直到亚硝基被消除,然后沉淀,回收有机相,可选地用水洗涤,然后通过在减压下蒸发有机溶剂来分离烷氧胺。
