Magnetically Recyclable Silica-Coated Magnetite-Molybdate Nanocatalyst and its Applications in N-Formylation Reactions Under Solvent-Free Conditions

Abstract

A novel magnetite silica-coated nanoparticle-supported molybdate nanocatalyst has been prepared successfully by a simple co-precipitation method. Prepared nanocatalyst has been characterized by different techniques like Fourier Transmission Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FE-SEM) and Energy Dispersive X-ray Spectroscopy (EDX). Further, the catalytic activity of the nanocatalyst was explored for N-formylation reactions under solvent-free conditions. Interestingly, the catalyst could be reused for 10 cycles and only 2 mol % of the catalyst was sufficient to catalyze the N-formylation reaction at 700C under solvent-free conditions.

Magnetically Recoverable Silica-Decorated Ferromagnetic-Nanoceria Nanocatalysts and Their Use withO- andN-Butyloxycarbonylation Reaction via Solvent-Free Condition

“…Nanoparticle development has piqued the interest of researchers in recent decades. Certain functionalized nanoparticles appear to be particularly reactive due based on the evidence of nanomaterial formed by some of the more active centers. , Ferrite magnetic nanoparticles have been extensively employed in the manufacturing industries and in medical applications such as drug development . The much more common uses for magnetite nanoparticles are in chemical synthesis, including the manufacture of Suzuki coupling reaction, alkynyl chalcogenide, synthesis of quinoxaline, 3,4-dihydropyrimidine-2-(1 H ), calix-4-resorcinarenes, pyranopyrazoles, α-amino nitriles, synthesis of sulfonamide, α-aminophosphonate, the Sonogashira-Hagihara reaction, propargylic amine synthesis, and acylation reaction, etc.…”
