Abstract

ABSTRACT: An oxyphosphate of formula BiCa4 (PO4 )3 O was prepared and characterized by powder XRD, Fourier transform infrared spectroscopy (FTIR), and SEM-EDAX techniques. The catalytic activity of the synthesized compound was explored in the preparation of 3, 4-dihydropyrimidin-2(1 H )-one using Biginelli reaction. Influence of parameters such as temperature and solvent on this reaction using this heterogeneous catalyst was studied. A higher yield of 98% of the 3, 4-dihydropyrimidin-2(1 H )-one was achieved within 120 min of duration at room temperature in the presence of acetic acid (AcOH).
