[ 1 ] - Fe-MCM-22 catalyzed multicomponent synthesis of dihydropyrano [2,3-c] pyrazole derivatives

The Fe-MCM-22 zeolite was found to be an efficient solid heterogeneous catalyst for synthesis of dihydropyrano [2,3-c] pyrazoles via one pot four component reaction of ethyl acetoacetate, hydrazine hydrate, aromatic aldehyde and malononitrile in aqueous alcohol. The catalyst was synthesized by hydrothermal method under autogenous pressure and modified by Fe (III) ion exchange. The prepared cata...

[ 2 ] - Mesolite catalyzed one pot synthesis of quinoline-3-carbonitrile derivatives

Natural mesolite type zeolite was collected, modified by sulfuric acid treatment and characterized by using Powder-X ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR).Temperature programmed ammonia desorption (NH3-TPD), Brunauer-Emmer-Teller (BET) surface area analysis. Modified dealuminat...

[ 5 ] - Ce-ZSM-11 Zeolite: An Efficient Heterogeneous Catalyst for One-Pot Synthesis of 4H-Pyran Derivatives

ZSM-11 zeolite was synthesized by hydrothermal treatment and cerium ion was incorporated by the ion exchange method. The catalytic activity of cerium modified ZSM-11 zeolite was tested for the one-pot synthesis of 4H-pyran derivatives by cyclocondensation of aromatic aldehyde, malononitrile, and ethyl acetoacetate. The synthesized catalyst was characterized by Po...
