ABSTRACT:
Aromatic tertiary amines are oxidized by means of hydrogen peroxide in an inert solvent medium in the presence of a catalyst selected from metal selenium and compounds of selenium.
The process is applied to the preparation of oxides of heterocyclic aromatic tertiary amines and oxides of non-heterocyclic tertiary amines, in which the nitrogen atom is substituted by at least 1 aromatic nucleus.
