Green Synthesis of N-pyrroles in Water via Using ZrOCl2.8H2O as an Efficient and Eco-Friendly Catalyst
A simple and efficient protocol for the synthesis of N-substituted pyrroles from one-pot condensation reaction of 2, 5-dimethoxytetrahydrofuran with aryl/alkyl, sulfonyl and acyl amines in the presence of ZrOCl2•8H2O in water has been developed. This new method has the advantages of simple experimental and work-up procedure, high to excellent yields, easy availability, economical, eco-frien...
متن کاملCuO-CeO2 nanocomposite: A green recyclable catalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones
CuO-CeO2 nanocomposite is reported as a green and highly efficient recyclable catalyst for the multicomponent synthesis of 3,4-dihydropyrimidin-2(1H)-ones/thiones under solvent-free conditions. The catalyst was synthesized by co-precipitation method and characterized by XRD, BET specific surface area, FESEM and EDS analysis.
متن کاملEco-Friendly Synthesis and Characterization of Ni-Si Nanoparticles Mixed Oxides as Catalyst for
The nanoparticles of Ni–Si mixed oxides were prepared by co-precipitation method using nickel nitrate; Ni(NO3)2 6H2O and tetraethylorthosilicate (TEOS). The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and hydrogen temperature program reduction (H2-TPR). The results revealed that Ni–Si mixed oxides particles were obtained with average particle ...
