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.
公式为 ##STR1## 的N-烃氧化合物,其中E.sub.1、E.sub.2、E.sub.3和E.sub.4各自独立地表示有机基团,以使它们附着的碳原子均为季碳,R表示烃基团,T表示二价基团,可以直接通过在烃有机溶剂中使用
