Nano-TiO<sub>2</sub>: An Eco-Friendly and Clean Reusable Heterogeneous Catalyst for Preparation of α-Aminophosphonates Under Ambient and Solvent-Free Conditions
Abstract A one-pot catalytic three-componentsynthesis of α-aminophosphonates from arylaldehydes, anilines, and triethylphosphite by employing TiO2 nanoparticles as a catalyst is described. Nano-TiO2 has been found to be an excellent catalyst for the greensynthesis of α-aminophosphonates under ambient and solvent-free conditions. This green and mild nano catalytic procedure showed good recyclability
