Description
Summary:In this research, synthesis and characterization of a novel Schiff base Cu (II) complex immobilized on Fe 3 O 4 @SiO 2 nanoparticles are reported. Then, the catalytic activity of these nanoparticles as magnetic recyclable nanocatalyst was explored for the one-pot three-component synthesis of quinolin-5-one, chromene-3-carbonitrile and phthalazine-5,10-dione derivatives. The reactions proceeded smoothly to provide the respective products in excellent yields under green conditions. Facile preparation of the catalyst, high yields of the products, low reaction times, and use of water as green solvent are the main advantages of the present protocol. Moreover, the catalyst can be easily separated from the reaction mixture in a magnetic field, recycled and reused for six consecutive fresh runs without considerable loss of catalytic activity.
