    摘要: Nitroxyls 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 and T is a divalent radical are prepared by the oxidation of the corresponding amine in an inert organic solvent with a hydroperoxide in the presence of a metal carbonyl, metal oxide or metal alkoxide catalyst in high yield and purity. The nitroxyls may be directly reduced to the corresponding hydroxylamines by catalytic hydrogenation. The nitroxyls are useful as polymerization inhibitors and the hydroxylamines as polymer stabilizers.
