Abstract
A nitrone is synthesized from a secondary amine by reacting a compound represented by the following general formula ##STR1## wherein R.sup.1 and R.sup.2 mean individually a hydrogen atom or an alkyl or aryl group and R.sup.3 denotes an alkyl or aryl group with a peroxide in the presence of a catalyst selected from the group consisting of tungsten compounds, molybdenum compounds, vanadium compounds, titanium compounds, palladium compounds, rhodium compounds, ruthenium compounds and nickel compounds. This process provides the nitrone by one-step oxidation of the secondary amine.
