A convenient and efficient method has been developed for the synthesis of nitrone compounds. Nitrone derivatives were synthesized in good yields via a green chemistry procedure using diaminoglyoxime and aldehyde or ketones in the presence of ZnO nanoparticles (NPs) as a catalyst in H2O as a solvent at room temperature. After the reaction course, ZnO NPs can be recycled and reused without any apparent loss of activity which makes this ecofriendly process cost effective. The structures of the compounds were characterized using IR, 1HNMR, 13CNMR and mass analysis.
