Abstract

Ti–Al/Al2O3 NANOCOMPOSITE catalyzed green and efficient synthesis of 2-amino-4H-chromen-5 (6H) -ones via three-component condensation reaction of different aromatic aldehyde, malononitrile and dimedone in aqueous media. The reaction was preceded to completion within 30–90 min in 80–96 % yield at ambient temperature. The Ti–Al/Al2O3 NANOCOMPOSITE was prepared by milling for 4 h and combustion synthesis at 800 °C in the air atmosphere. The catalyst was well characterized by X-ray diffraction; laser particle sizer and transmission electron microscopy. Its average particle size was found to be around 27 nm. Reusability of the system was assured carrying out multiple runs using the recycled catalyst.
