    Abstract: In one embodiment, the present invention relates to a method of preparing a hydroxylammonium salt, involving the steps of: providing an electrochemical cell containing an anode, a cathode, and a divider positioned between the anode and the cathode, to define a catholyte compartment between the cathode and the divider and an anolyte compartment between the anode and the divider; charging the catholyte compartment with a first solution comprising a nitrogen containing compound and a mediator and the anolyte compartment with a second solution comprising an ionic compound; passing a current through the electrochemical cell to produce a hydroxylammonium salt in the catholyte compartment; and recovering the hydroxylammonium salt from the catholyte compartment. In another embodiment, the present invention relates to a method of preparing hydroxylamine, involving the steps of: providing an electrochemical cell containing an anode, a cathode and a divider positioned between the cathode and the anode, to define a catholyte compartment between the cathode and the divider, and an anolyte compartment between the divider and the anode; charging the catholyte compartment with a solution comprising a hydroxylammonium salt and a mediator, and the anolyte compartment with a first electrolyte solution; passing a current through the electrochemical cell to produce hydroxylamine in the catholyte compartment; and recovering hydroxylamine from the catholyte compartment.

    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.
