A novel fluorous bis(oxazolines) ligand was synthesized with 70% overall yield in 5 steps starting from 5-aminoisophthalic acid. The ligand was applied in the one-pot synthesis of α-aminophosphonates via copper-catalyzed Kabachnik-Fields reaction, giving the corresponding products in moderate to excellent yields under mild conditions. Furthermore, the fluorous ligand could be easily recovered and reused for four times without significant loss of activity.

Abstract: The design and application of environmentally friendly catalysts to reduce the quantity of toxic wastes is critical for improving?the chemical synthesis process. Therefore, BaFe12O19/Al2O3, a magnetic mesoporous nanocomposites, were designed synthesized and characterized using different techniques such as energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller?(BET) adsorption method, and vibrating sample magnetometry (VSM). The prepared BaFe12O19/Al2O3 display a high surface area (1773.22?m2/g) with an average pore diameter of 3.946?nm from nitrogen sorption analysis. In addition, the synthesized nanocomposites prove to be an active heterogeneous Lewis acid catalyst for the solvent free synthesis of α-aminophosphonates at ambient temperature, through three-component reaction of aldehydes/ketones, amines and triethyl phosphite. The use of this catalyst results in an effortless magnetic recoverability and recyclability, high yield and short reaction time under solvent-free conditions.

The choline based Zn containing deep eutectic mixture was applied as an efficient and eco-friendly ionic liquid catalyst for the one pot three-component synthesis of α-aminophosphonates under solvent-free condition at room temperature. The reactions were completed in short times and products were obtained in good to excellent yields.
