ABSTRACT:
The subject of the present invention is a new process for obtaining nitrones. It more particularly relates to a process for obtaining N-monosubstituted hydroxylamine comprising a stage in which a nitrone is formed from a secondary amine in the presence of an oxidizing agent and of at least one C.dbd.O containing species chosen from the group consisting of carbon dioxide, hydrogencarbonates and carbonates.
