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
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

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 alpha-aminophosphonates under solvent-free condition at room temperature. The reactions were completed in short times and products were obtained in good to excellent yields. (C) 2012 Elsevier Ltd. All rights reserved.

environmentally friendly catalyst, at ambient temperature. The catalyst exhibited remarkable activity and tolerated a wide variety of functional groups, providing the desired amino phosphonates in excellent yields undersolvent-freeconditions. Alternatively, the reaction rate can be significantly enhanced by carrying out the reaction in a monomode microwave reactor as a promoter.
