Preyssler heteropoly acid supported on silica coated NiFe2O4 nanoparticles for the catalytic synthesis of bis(dihydropyrimidinone)benzene and 3,4‐dihydropyrimidin‐2(1H)‐ones
electron microscopy, transmission electron microscopy, X-ray diffraction, energy dispersive spectrum, VSM and particle size neasurement. Its catalytic activity was investigated for the synthesis of bis(dihydropyrimidinone)benzene and 3,4-dihydropyrimidin-2(1...
Punica granatum peel: an organocatalyst for green and rapid synthesis of 3,4-dihydropyrimidin-2 (1H)-ones/thiones under solvent-free condition
A novel and green approach was adopted for the synthesis of 3,4-dihydropyrimidin-2(1H)-one/thiones derivatives using Punica granatum peel as an inexpensive, efficient and mild catalyst under solvent-free condition. The methodology is characterized...
1,3Dichloro-5,5-dimethylhydantoin as a Novel and Efficient Homogeneous Catalyst
A new and efficient method for the preparation of substituted 3,4-dihydropyrimidin-2(1H)-ones via Biginelli synthesis
using catalytic amounts of 1,3-dichloro-5,5-dimethylhydantoin is presented. Short reaction times, easy work-up, high...
