N-hydrocarbyloxy compounds of the formula ##STR1## where E.sub.1, E.sub.2, E.sub.3 and E.sub.4 are independently an organic radical so that the carbon atoms to which they are attached are each a quaternary carbon, R is a hydrocarbon radical and T is a divalent radical are prepared directly by the reaction of the corresponding amine or oxyl compound in a hydrocarbon organic solvent with a hydroperoxide in the presence of a metal carbonyl, metal oxide or metal alkoxide catalyst in high yield and purity. These compounds are useful as light stabilizers in diverse substrate systems.
根据公式##STR1##制备的N-烃氧基化合物,其中E.sub.1、E.sub.2、E.sub.3和E.sub.4分别是有机基团,使得它们连接的碳原子均为四级碳,R是烃基团,T是二价基团,通过在烃有机溶剂中,将相应的胺或氧基化合物与
过氧化氢在
金属羰基、金属氧化物或
