Preparation, characterization and catalytic application of molybdenum Schiff-base complex immobilized on silica-coated Fe3O4 as a reusable catalyst for the synthesis of pyranopyrazole derivatives

A recoverable molybdenum Schiff-base complex immobilized on silica-coated Fe3O4 nanoparticles was prepared and characterized. This superparamagntic nanocatalyst, which is separable using an external magnet, can be used as an efficien

Zn (II)-Schiff base covalently anchored to CaO@SiO2: A hybrid nanocatalyst for green synthesis of 4H-pyrans

In this study, the Zn (II)-Schiff base covalently anchored onto the surface of CaO@SiO2 nanoparticles. The structure of this hybrid nanomaterial (CaO@SiO2-NH2-Sal-Zn) was characterized using the analytical techniques such

Sulfonic acid-functionalized Fe3O4-supported magnetized graphene oxide quantum dots: A novel organic-inorganic nanocomposite as an efficient and recyclable nanocatalyst for the synthesis of dihydropyrano[2,3-c]pyrazole and 4H-chromen

In this research, the main emphasis has been focused on the preparation of a novel Fe3O4-supported propane-1-sulfonic acid-grafted graphene oxide quantum dots (Fe3O4@GOQD-O-(propane-1-sulfonic acid)) that it was

Environmentally benign synthesis of pyranopyrazole derivatives by cobalt Schiff-base complexes immobilized on magnetic iron oxide nanoparticles

In this work, an efficient and straight procedure has been described for one-pot three-component synthesis of pyranopyrazole derivatives in the presence of a new cobalt Schiff-base complex immobilized on silica-coated Fe3O4 nanoparti

Amberlite-supported L-prolinate: A novel heterogeneous organocatalyst for the three-component synthesis of 4H-pyrano[2,3-c]pyrazole derivatives

This report describes a new and convenient procedure for heterogenization of L-proline organocatalyst, which is based on non-covalent immobilization of L-proline on the surface of anion-exchange resin amberlite IRA900OH (AmbIRA900OH) as an efficient, chea

Piperidine-Promoted Three-Component Condensation: Synthesis of Chromene Heterocycles and Pyrazolotriazoles

Chromenes, the oxygen-containing heterocyclic compounds, have a “special” place in biologically active natural products and in synthetic chemistry and in the fields of medicinal, agrochemical, cosmetic, and pigment industries. In this work, piperidine was used as a base catalyst for the convenient synthesis of 1,4-dihydropyrano[2,3-c]pyrazole, 5,10-dihydro-4H-benzo[g]chromene, and pyrazolo[1,2-a] [1,2,4]triazole derivatives at ambient temperature. This methodology has several advantages including the use of easily accessible and inexpensive catalysts, short reaction times, high yields, convenient work-up, and not needing column chromatography.

Ag/Tio2 nano thin films catalyzed efficient synthesis of 6-amino-4-aryl-3-methyl-1,4-dihydropyrano[2,3-C] pyrazole-5-carbonitriles at green conditions

Ag/TiO2 nano thin films was found to be efficient and green heterogeneous catalyst for the synthesis of dihydropyrano[2,3-c]pyrazole derivatives via a one-pot three-component reaction between 3-methyl-1H-pyrazol-5(4H)-one or 3-methyl-1(phenyl)-

Catalytic applications of {[HMIM]C(NO2)3}: As a nano ionic liquid for the synthesis of pyrazole derivatives under green conditions and a mechanistic investigation with a new approach

Catalytic applications of 1-methylimidazolium trinitromethanide {[HMIM]C(NO2)3}as the first nano ionic liquid (NIL) was studied. The described NIL was efficiently tested in the synthesis of 5-amino-pyrazole-4-carbonitrile derivatives

Tin sulfide nanoparticles supported on activated carbon as an efficient and reusable Lewis acid catalyst for three-component one-pot synthesis of 4H-pyrano[2,3-c]pyrazole derivatives

Tin sulfide nanoparticles (SnS-NPs) were prepared in aqueous solution at room temperature on the surface of activated carbon (AC) and were investigated using field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-r
