Abstract

In this work, preparation and crystallization of yttrium iron garnet Y3Fe5O12 super-paramagnetic nanoparticle by aqueous sol–gel processes and its application as an effective nano catalyst for esterification and etherification reactions in short reaction time and in high isolated yields. Then this catalist was used for the synthesis of Dihydropyrimidin derivatives is described. The catalyst was identified by FT-IR spectroscopy, scanning electron microscopy (SEM), Transmission electron microscopy (TEM) , X-ray diffraction (XRD) , vibrating sample magnetometer(VSM) analysis.
