    摘要: Sterically hindered N-hydrocarbyloxyamines are prepared from hindered amine N-oxyl compounds by a process which uses hydrogen peroxide or a hydrogen peroxide equivalent, a catalytic amount of a peroxide decomposing transition metal salt, metal oxide, or metal-ligand complex, a hydrocarbon solvent containing no activated hydrogen atoms, and a relatively inert cosolvent. These compounds are useful as thermal and light stabilizers for a variety of organic substrates.
