Synthesis of ۳,۴,۵-substituted furan-۲(۵H)-ones using nano-NiZr۴(PO۴)۶ as catalyst under ultrasonic irradiation

چکیده مقاله

In the present paper, we report the synthesis of nanocrystalline NiZr4(PO4)6. This nano-structure was characterized by X-ray diffraction, scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). Size of nano-structures was in the range of nanometers. Nano NiZr4(PO4)6 as an efficient and green catalyst has been used for the preparation of 3,4,5-substituted furan-2 (5H)-ones through a three-component reaction of amines, dialkyl acetylene dicarboxylate, and aromatic aldehydes.
