FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for preparing aminoxyl ethers, for example, N-hydrocarbyloxy-derivatives of steric hindranced amines that can be used as light- and/or thermostabilizing organic materials and/or a regulator in the polymerization reaction. Invention describes a method for preparing aminoxyl ethers by interaction of the corresponding N-oxyl derivative with hydrocarbon organic solvent in the presence of organic peroxide and a catalyst representing copper or copper compound, preferably, inorganic compound Cu (I) or Cu (II) as a solution in suitable solvent chosen in the catalytically effective amount. Method provides preparing the end product with the high yield by simplified technological schedule and without using high temperatures.
EFFECT: improved method of synthesis.
