    Abstract A novel magnetic acidic catalyst comprising Preyssler (H 14 [NaP 5 W 30 O 110 ]) heteropoly acid supported on silica coated nickel ferrite nanoparticles (NiFe 2 O 4 @SiO 2 ) was prepared. The catalyst was characterized by Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, energy dispersive spectrum, VSM and particle size neasurement

    A green and highly efficient approach for the synthesis of 3,4-dihydropyrimidine-2(1H)-one/thione derivatives is described. In this approach, the three-component Biginelli reaction between (thio)urea, methyl acetoacetate and aldehydes under solvent-free condition in the presence of chitosan-silica sulfate nano hybrid (CSSNH) as a green and heterogeneous nano catalyst affords the corresponding products in good to excellent yields and in short reaction times. CSSNH is a cheap, eco-friendly, and non-toxic nano catalyst that could be easily prepared, handled, and reused for many reaction runs without significant loss of its activity.
