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. Graphical Abstract Unsupported ‘free' nano-SiO2 has been shown to be a stable yet highly active catalyst for preparing a variety of a-aminophosphonates from one-pot three-component condensation reaction.
