Ionicliquid ethyl ammonium nitrate is used as an excellent catalyst and solvent for three-component one-pot reaction of an aldehydes, amines and diethylphosphite to form novel α-aminophosphonates at room temperature. Among the various catalysts, the preparation of ethyl ammonium nitrate is an environmental friendly, cost effective and recyclable catalyst. Compounds 4b, 4c, 4d, 4f and 4j were found
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
