Caffeine-loaded Fe3O4 nanoparticles: A new magnetically recoverable organocatalyst for Knoevenagel condensation reaction

Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometer (VSM). The resulting nanocom...

Fe3O4@mesoporous SBA-15: a robust and magnetically recoverable catalyst for one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones via the Biginelli reaction.

A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles with functionalized mesoporous SBA-15. Functionalized mesoporous SBA-15 containing surface carboxyl and amino groups was synthesized via the thiol-ene click reaction of cysteine hydrochloride and vin...

Nanoparticle-supported and magnetically recoverable palladium (Pd) catalyst: a selective and sustainable oxidation protocol with high turnover number.

A magnetic nanoparticle-supported Pd catalyst was readily prepared from inexpensive starting materials and shown to catalyze various oxidation reactions with high turnover number (TON) and excellent selectivity. The ease of recovery using an external magnetic field, high activity, and the intrinsic stability of the catalyst make this protocol economic and sustainable.

Boric Acid-Functionalized Fe3O4@SiO2 as a Novel Superparamagnetically Recoverable Nano Catalyst for Mukaiyama-Aldol Reaction

We have reported the fabrication of boric acid incorporated into surface of magnetite nanoparticles. The catalyst was characterized using spectroscopic, magnetic and thermal techniques (FT-IR, SEM, XRD, ICP, VSM and TGA). It catalyzed Mukaiyama aldol reaction of a ketene silyl acetal type nucleophile ((1-methoxy-2-methylprop-1-enyloxy) trimethylsilane), and various aldehydes (aromatic, aliphati...
