ZnO NPs: an efficient and reusable nanocatalyst for the synthesis of nitrones from DAG using H2O as a solvent at room-temperature

Abstract

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 H 2 O 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, 1 HNMR, 13 CNMR and mass analysis.
