The palladium (Pd) supported on thio-modified multi walled carbon nanotubes (MWCNTs/CC-SH/Pd) was utilized as a useful and reusable nanocatalyst in Suzuki-Miyaura coupling reactions. The catalyst was really efficient for the Suzuki-Miyaura reaction of aryl halides (Ar-I, Ar-Br, Ar-Cl) with phenylboronic acid and conversion was good in most cases. The aryl iodides and aryl bromides reactions take place at room temperature, while reaction of aryl chlorides occurred at temperature of 80°. The products yields ranged between70% and 96%. The catalyst indicated excellent constancy and could be recycled and reused up to four cycles with no considerable change in its catalytic behavior.

In this study, Pd nanoparticles supported on Metformin modified graphene oxide (GO-Met-Pd) is proposed as a green heterogeneous catalyst. The structural properties of the as-synthesized nanocatalyst were determined by X-ray diffraction (XRD), Fourier transformed IR (FT-IR) spectroscopy, transmission electron microscopy (TEM), field emission SEM (FESEM), energy dispersive X-ray spectroscopy (EDS), wavelength-dispersive X-ray spectroscopy (WDX) and inductively coupled plasma (ICP). Activity of the catalyst was investigated by focusing on the Suzuki-Miyaura coupling reaction and room-temperature reduction of 4-nitrophenol (4-NP), as model reactions. The catalyzed reactions provided high yields of biphenyl compounds through the Suzuki-Miyaura reaction and outlined highly efficient conversion of 4-NP to its reduced form. Moreover, no significant Pd leaching was detected in the reaction solutions and the catalyst could be recovered, at least, 6 times without any considerable loss of its catalytic activity. The experimental part of the paper was very detailed, including the reaction process of 1-Iodo-4-methylbenzene(cas: 624-31-7Reference of 1-Iodo-4-methylbenzene)
