《L-Methionine-Pd complex supported on hercynite as a highly efficient and reusable nanocatalyst for C-C cross-coupling reactions》 was written by Mohammadi, Masoud; Ghorbani-Choghamarani, Arash. COA of Formula: C7H4BrN And the article was included in New Journal of Chemistry in 2020. The article conveys some information:
A ”green” method was suggested for the synthesis of hercynite magnetic nanoparticles (MNPs) as a novel heterogeneous catalytic support to immobilize homogeneous complexes, L-Methionine-Pd was immobilized on the surface of hercynite MNPs by a simple, rapid, and convenient route. The structure and composition of the prepared Hercynite@L-Methionine-Pd MNPs were characterized by X-ray diffraction spectroscopy, energy-dispersive X-ray spectroscopy, inductively coupled plasma-optical emission spectrometry, SEM, X-ray mapping, thermogravimetric anal. and vibrating-sample magnetometry (VSM). Besides, they were applied as green nanocatalysts for Suzuki and Heck cross-coupling reactions. Hercynite@L-Methionine-Pd MNPs offer several advantages (simple synthetic method under green conditions, thermal and chem. stability during organic reactions, short reaction times, high yields of products, excellent selectivity and easy work-up procedure). Moreover, the recycled nanocatalyst was reused for at least five cycles with no significant loss of activity. The hot filtration test indicated heterogeneous catalysis for Suzuki and Heck cross-coupling reactions. This work is useful for the development and application of a magnetically recoverable Pd nanocatalyst on the basis of green-chem. principles. After reading the article, we found that the author used 4-Bromobenzonitrile(cas: 623-00-7COA of Formula: C7H4BrN)
4-Bromobenzonitrile(cas: 623-00-7) is classified as organic nitriles, which are commonly use solvents and are reacted further for various applications such as manufacture of polymers and intermediates for pharmaceuticals and other organic chemicals,COA of Formula: C7H4BrN It can also be used as an aryl halide test compound in developing greener reaction conditions for Suzuki cross-coupling between aryl halides and phenyl boronic acid.
