《New Nanomagnetic Heterogeneous Cobalt Catalyst for the Synthesis of Aryl Nitriles and Biaryls》 was published in ACS Omega in 2020. These research results belong to Moghadam, Hadis Hosseini; Sobhani, Sara; Sansano, Jose Miguel. COA of Formula: C7H4FN The article mentions the following:
Cobalt nanoparticles immobilized on magnetic chitosan (Fe3O4@CS-Co) have been prepared They were identified using various techniques such as Fourier-transform IR spectroscopy, X-ray diffraction, field emission SEM, energy-dispersive X-ray spectroscopy, transmission electron microscopy, thermogravimetric anal., vibrating sample magnetometry, XPS, and inductively coupled plasma at. emission spectroscopy anal. and applied efficiently as a cobalt catalyst in the cyanation and fluoride-/palladium-free Hiyama reactions of different types of aryl halides ArX (Ar = Ph, 4-iodophenyl, pyridin-3-yl, etc.; X = I, Br, Cl) employing K4[Fe(CN)6].3H2O and triethoxyphenylsilane, resp. After each reaction, the catalyst was isolated and reused for the second run. The catalytic activity of the catalyst was not lost apparently even after five runs. No considerable changes in its chem. structure and morphol. were observed It is worth to note that in this paper, the cobalt catalyst has been used for the first time for the cyanation of aryl halides. In addition to this study using 4-Fluorobenzonitrile, there are many other studies that have used 4-Fluorobenzonitrile(cas: 1194-02-1COA of Formula: C7H4FN) was used in this study.
4-Fluorobenzonitrile(cas: 1194-02-1) is used in the synthesis of flurenones, pharmaceutical prerequisites, as well as opiod receptor antagonists.COA of Formula: C7H4FN
