摘要：Magnetic nanoparticle -Fe2O3-immobilized 1,5,7-triazabicyclo[4.4.0]dec-5-ene as a novel magnetic nanocatalyst was synthesized and characterized. The nanoparticle reagent catalyzed efficiently the synthesis of -oxindole--hydroxyphosphonates from isatins and dimethyl phosphate under solvent-free conditions at 60 degrees C. More importantly, the catalyst could be easily recovered by an external magnet and reused six times without significant loss of activity. Copyright (c) 2014 John Wiley & Sons, Ltd.
