  reaction of isatins, imines, and aldehydes using dimethyl and diethyl phosphite as a nucleophile to give the corresponding α‐hydroxy and α‐amino phosphonates in excellent yields for a wide range of substrates. The reaction conditions were simple, green, and efficient. The catalyst was recycled up to five times with retention of its activity. Based on the NMR spectroscopy studies, a probable catalytic cycle

  A simple, efficient, eco-friendly, and cost-effective method has been developed for the synthesis of α1-oxindole-α-hydroxyphosphonate derivatives (3a–o) by a one-pot reaction of isatins (1a–o) with trialkyl phosphites (2a–o) under catalyst-free-conditions using inexpensive, non-toxic polyethylene glycol (PEG-400) in excellent yields (82–92%). The present methodology offers an environmental acceptability;

  Magnetic nanoparticle γ‐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 α′‐oxindole‐α‐hydroxyphosphonates from isatins and dimethyl phosphate under solvent‐free conditions at 60 °C. More importantly, the catalyst could be easily recovered by an external magnet and
