Here we report a paired electrochemical coupling of readily accessible nitro-compounds with benzyl alcohols to yield nitrone derivatives. In this work, electrochemical behavior of nitrobenzene and benzyl alcohol derivatives was studied by cyclic voltammetry and controlled potential coulommetry. Electrochemical reactions have been performed in aqueous/ethanol (or acetonitrile) solutions by employing

A mild and facile reduction of nitroarene with aromatic aldehydes promoted by metallic samarium to C, N-diaryl nitrones in moderate yields has been developed.
metal-free approach for the ʟ-proline mediated synthesis of nitrones from nitrosobenzene and benzaldehydes has been established. The reaction undergoes very efficiently at room temperature in methanol as a solvent. The reaction is assumed to involve that the initial formation of azomethine ylide and [2 + 3] cycloaddition of nitrosobenzene, followed by the subsequent retro [2 + 3] cycloaddition could offer

An efficient, simple and selective method for the deoxygenation of aromatic N-oxides, such as N-arylnitrones, azoxybenzenes, N-heteroarene N-oxides using ruthenium(III) chloride to afford deoxygenated products in excellent yields, is described.

The reaction of prop-1-ene-1,3-sultone (1) with a variety of nitrones 2 afforded novel [3+2] cycloaddition products 3, 4, and 5 in good yield. Excellent regio- and stereoselectivity were achieved in the cycloaddition reaction with phenylnitrones.
