    • Abstract

       

      Nano-SiO2 catalyst was readily prepared from inexpensive starting materials in aqueous media which catalysed the synthesis 𝑎-aminophosphonates from aldehydes, amines and diethylphosphate under ultrasonication in water. High catalytic activity and ease of recovery from the reaction mixture using filtration, and reuse without significant losses in performance are additional eco-friendly attributes of this catalytic system.
