“…Furthermore, by Fig. 9 XPS spectra of the fresh and recycled IRMOF-3-Pd increasing the reaction temperatures (entries 25 to 28) reaction rate increases linearly which is explained typically by Arrhenius type dependence of the rate constants on temperature as well as by a faster redisposition of Pd on the catalyst at elevated temperature [41]. The apparent activation C Pd energy (Fig.…”

Pd Supported IRMOF-3: Heterogeneous, Efficient and Reusable Catalyst for Heck Reaction

et al. 2019

View full text Add to dashboard Cite

IRMOF-3 with a high surface area prepared by a hydrothermal method was used for deposition of Pd(OAc) 2 on IRMOF-3 particles. The final catalyst was characterized with FT-IR, nitrogen physisorption, thermogravimetry, scanning electron microscopy, transmission electron microscopy combined with energy dispersive X-ray analysis, wide angle X-ray diffraction spectroscopy and X-ray photoelectron spectroscopy. The prepared porous catalyst was effectively used in the Heck coupling reaction in the presence of an organic base. The reaction parameters such as the type of base, amounts of catalyst and solvents, temperature were optimized. The catalyst was then easily separated, washed, and reused 4 times without significant losses of catalytic activity.

“…These compounds, in general, are considered the most reactive in the Heck reaction making them the most convenient for testing new materials, such as the catalyst developed in the current work. In generally, less reactive compounds would require prolonged reaction times or elevated temperatures [14,[56][57][58].…”

Magnetic particles were prepared by a hydrothermal method and then successively covered by Metal-Organic-Frameworks MIL-101-NH 2 with a high surface area. This was followed by deposition of Pd(OAc) 2 on Fe 3 O 4-NH 2 @MIL-101-NH 2 particles. The final catalyst was characterized with FT-IR, nitrogen physisorption, thermogravimetry (TGA), scanning electron microscopy (SEM) combined with energy dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), wide-angle X-ray diffraction spectroscopy (XRD) and X-ray photoelectron spectroscopy (XPS). The prepared magnetic catalyst was effectively used in the Heck coupling reaction in the presence of an inorganic base. The reaction parameters such as the base type, amounts of catalyst and solvents, temperature, and substrates ratios were optimized. The catalyst was then magnetically separated, washed, and reused 7 times without losing significantly catalytic activity.

“…[9][10][11][12][13][14][15][16][17][18] Reactions of this type have been intensively investigated in some variants with respect to the kind of used substrate such as arylation of dihydrofuran (DHF). [19][20][21][22][23][24] This P-free catalytic processes in spite of various advantages such as better commercial and ecological properties in compared to phosphine/palladium catalysts, exhibited lower selectivity. These approaches employing aryl triflate substrate and numerous phosphine backbone ligands such as amide-based phosphite-oxazolines, 11 atropisomeric P,O-ligands, 16 benzylically substituted P,Nligands, 17 and diphosphine-oxazoline ferrocenyl 18 in presenting of palladium salts.…”

This is the first report of regioselective Heck reaction of aryl iodides with 2,3-dihydrofuran using heterogonous nanocatalyst. Herein, palladium nanoparticles is immobilized on DNA-modified multi walled carbon nanotubes and characterized by FT-IR spectroscopy, UV-vis spectroscopy, field emission scanning electron microscopy, X-ray diffraction, transmission electron microscopy, inductively coupled plasma and elemental analysis. DNA as a welldefined structure and biodegradable natural polymer generate the palladium catalyst which showed high activity in common and regioselective Heck reaction in excellent yields and good selectivity under ligand-free and mild reaction conditions. Moreover, the catalyst could be recovered and reused at least nine times without any considerable loss of its catalytic activity.
