Abstract A novel application of nanoparticles paramagnetic magnetite (Fe 3 O 4 ) as an efficient catalyst for carbon‐carbon bond formation via the Sonogashira–Hagihara reaction under heterogeneous ligand‐free conditions in ethylene glycol (EG) is described. By using this catalyst, arylalkynes are produced from aryl iodides and activated heteroaryl bromides with alkynes. The results reproducible which was prepared different sources. easily separated by external magnetic field mixture. can be...
A novel gold nanoparticle supported periodic mesoporous organosilica with alkylimidazolium framework, Au@PMO-IL, was shown to be a highly active and recyclable catalyst for three-component coupling reaction of aldehyde, alkyne amine give the corresponding propargylamine.
Abstract In this article, we have developed a new protocol for the thioarylation of structurally diverse alkyl bromides such as benzyl, cinnamyl, n ‐octyl, cyclohexyl, cyclopentyl, and tert ‐butyl with aryl iodides, an activated chloride using thiourea catalyzed by copper(I) iodide in wet polyethylene glycol (PEG 200) eco‐friendly medium presence potassium carbonate at 80 100 °C under inert atmosphere. The process is free from foul‐smelling thiols which makes method more practical...
Bimetallic PdCu nanoparticles can be applied as catalysts in a wide range of chemical and electrochemical reactions.
Bimetallic Fe–Cu MOF was effectively synthesized through a one‐pot solvothermal process and successfully characterized by TEM, XPS, SEM, XRD, BET, EDX, elemental mapping, FT‐IR analysis. This bimetallic employed as catalyst in the reduction of nitroarenes at room temperature well dyes, for example, methyl orange (MO) methylene blue (MB). Results pointed to exhibiting outstanding catalytic performance both reactions. The activity comparison with Fe‐MOF Cu‐MOF indicated superior compared...
Novel supported noble metals, on an ionic liquid modified Fe-based metal–organic framework (MOF), are considered as efficient catalyst.
Zeolitic imidazolate framework‐67 (ZIF‐67) functionalized with graphene quantum dots was prepared and utilized for the reduction of Au (III) stabilization nanoparticles. This newly ZIF‐67/GQD@Au characterized different techniques employed as a capable heterogeneous catalyst aromatic nitro compounds A 1 ‐coupling reaction alkynes, amines, aldehydes in water solvent. Experiments indicate that this is able to reduce nitroarenes short times (10–20 min) at room temperature corresponding amines...
