Fe3O4@silica sulfuric acid nanoparticles: An efficient reusable nanomagnetic catalyst as potent solid acid for one-pot solvent-free synthesis of indazolo[2,1-b]phthalazine-triones and pyrazolo[1,2-b]phthalazine-diones
Ali Reza Kiasat,Jamal Davarpanah +1 more
TL;DR: In this paper, the preparation of sulfuric acid functionalized silica-coated magnetite nanoparticles with core-shell structure was presented by using Fe 3 O 4 spheres as the core and silica sulfic acid nanoparticles as the shell, and the ability of this nanomagnetic solid acid catalyst in the one-pot three-components condensation reaction of phthalhydrazide, aromatic aldehydes and cyclic or acyclic 1,3-diketones are also described.
Journal ArticleDOI
Nano magnetic double-charged diazoniabicyclo[2.2.2]octane dichloride silica hybrid: Synthesis, characterization, and application as an efficient and reusable organic–inorganic hybrid silica with ionic liquid framework for one-pot synthesis of pyran annulated heterocyclic compounds in water
TL;DR: In this article, the magnetic double-charged diazoniabicyclo[2.2] octane chloride silica hybrid, Fe 3 O 4 @SiO 2 /DABCO, was characterized by infrared spectroscopy, X-ray diffraction, scanning electron microscope (SEM), vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA), and differential thermal analysis (DTA).
Journal ArticleDOI
Catalytic application of silver nanoparticles immobilized to rice husk-SiO2-aminopropylsilane composite as recyclable catalyst in the aqueous reduction of nitroarenes
Jamal Davarpanah,Ali Reza Kiasat +1 more
TL;DR: In this paper, amorphous silica nanoparticles were taken from low-cost rice husk (RH-SiO 2 ) by carrying out an acid chemical treatment followed by the process of burning.
Journal ArticleDOI
Synthesis of 1,4-dihydropyridine and polyhydroquinoline derivatives via Hantzsch reaction using nicotinic acid as a green and reusable catalyst
TL;DR: In this article, a rapid, efficient and eco-friendly protocol has been developed for the preparation of various 1,4-dihydropyridine and polyhydroquinoline derivatives in the presence of nicotinic acid as a green and dual catalyst under solvent-free conditions.
Journal ArticleDOI
Nanomagnetic double-charged diazoniabicyclo(2.2.2)octane dichloride silica as a novel nanomagnetic phase-transfer catalyst for the aqueous synthesis of benzyl acetates and thiocyanates
Jamal Davarpanah,Ali Reza Kiasat +1 more
TL;DR: In this paper, a phase transfer catalyst for nucleophilic substitution reactions of benzyl halides was used for the synthesis of benyl acetates and thiocyanates in good to excellent yields at 100°C in water.
