The zinc chromium ferrite magnetic nanoparticles ZnCrFeO4: An efficient catalyst for acetylation of alcohols, phenols and amines under solvent-free conditions
Volume 6, Issue 2, pp. 109-217, Serial No. 19 , April 2018, , Pages 169-179
Abstract
In this study, the zinc chromium ferrite magnetic nanoparticles ZnCrFeO4 are synthesized via sol-gel method and characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The XRD analysis showed that ZnCrFeO4 has single-phase ... Read More)

Ag nanoparticle/melamine sulfonic acid supported on silica gel as an efficient catalytic system for synthesis of dihydropyrimidin thiones
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, , Pages 180-186
Abstract
3,4-dihydropyrimidin-2(1H)-thiones were synthesized in the presence of Ag nanoparticle/melamine sulfonic acid (MSA) supported on silica gel. The reaction was carried out at 110 oC for 20 min under solvent free conditions. In all cases, the three component reaction proceeded smoothly to give the corresponding ... Read More)
