The information in the text is summarized as follows:

A non-toxic cyanation reaction of various aryl halides and triflates in acetonitrile using a catalyst system of [Ni(MeCN)6](BF4)2, 1,10-phenanthroline, and 1,4-bis(trimethylsilyl)-2,3,5,6-tetramethyl-1,4-dihydropyrazine (Si-Me4-DHP) is developed.

《Cobalt-Catalyzed C(sp2)-CN Bond Activation: Cross-Electrophile Coupling for Biaryl Formation and Mechanistic Insight》 was published in ACS Catalysis in 2020. These research results belong to Dorval, Celine; Tricoire, Maxime; Begouin, Jeanne-Marie; Gandon, Vincent; Gosmini, Corinne. Safety of 4-Fluorobenzonitrile The article mentions the following:

Herein, we report a cross-electrophile coupling of benzonitrile derivatives and aryl halides with a simple cobalt-based catalytic system under mild conditions to form biaryl compounds Even though the cobalt catalyst is able to activate the C(sp2)-CN bond alone, the use of the AlMe3 Lewis acid enhances the reactivity of benzonitriles and improves the cross-selectivity with barely any influence on the functional group compatibility. X-ray structure determination of an original low-valent cobalt species combined with catalytic and stoichiometric reactions reveals a catalytically active cobalt(I) species toward the aryl halide partner. On the other hand, exptl. insights, including cyclic voltammetry experiments, suggest the involvement of a cobalt complex of a lower oxidation state to activate the benzonitrile derivative Finally, d. functional theory calculations support the proposed mechanistic cycle involving two low-valent cobalt species of different oxidation states to perform the reaction. The experimental part of the paper was very detailed, including the reaction process of 4-Fluorobenzonitrile(cas: 1194-02-1Safety of 4-Fluorobenzonitrile)

《A hydrophilic heterogeneous cobalt catalyst for fluoride-free Hiyama, Suzuki, Heck and Hirao cross-coupling reactions in water》 was written by Sobhani, Sara; Hosseini Moghadam, Hadis; Skibsted, Joergen; Sansano, Jose Miguel. SDS of cas: 623-00-7 And the article was included in Green Chemistry in 2020. The article conveys some information:

A hydrophilic heterogeneous cobalt catalyst of chitosan, denoted as mTEG-CS-Co-Schiff-base, has been successfully prepared This newly synthesized catalyst was characterized by different methods such as XRD, FE-SEM, TEM, TGA, FT-IR, 13C{1H} CP/MAS NMR, XPS and ICP analyses. The catalyst displayed excellent activity for the palladium and fluoride-free Hiyama, Suzuki, Heck and Hirao reactions of various aryl iodides 4-RC6H4I (R = H, OMe, Cl, I), bromides 4-R1C6H4Br (R1 = H, OMe, NO2, CN, Cl, Me, Br)/(2-bromoethenyl)benzene and chlorides 4-R2C6H4Cl (R2 = H, NO2, CN, Me) (i.e., the most challenging aryl halides which are cheaper and more widely available than aryl iodides and bromides) in water. The presence of triethylene glycol tags with hydrophilic character on the Co-complex supported on chitosan provides dispersion of the catalyst particles in water, which leads to higher catalytic performance and also facile catalyst recovery by successive extraction The catalyst was reused for at least six successive runs without any discernible decrease in its catalytic activity or any remarkable changes in catalyst structure. The use of water as a green solvent, without requiring any additive or organic solvent, as well as use of a low cost and abundant cobalt catalyst instead of expensive Pd catalysts along with the catalyst recovery and scalability, make this method favorable from environmental and economic points of view for the C-C and C(sp2)-P coupling reactions. Notably, this is the first report on the application of a cobalt catalyst in Hiyama reactions. In the experiment, the researchers used many compounds, for example, 4-Bromobenzonitrile(cas: 623-00-7SDS of cas: 623-00-7)

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,SDS of cas: 623-00-7 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.

The article was titled 《The Heck reaction of allylic alcohols catalysed by an N-heterocyclic carbene-Pd(II) complex and toxicity of the ligand precursor for the marine benthic copepod Amphiascoides atopus》.Synthetic Route of C7H4BrN The article contains the following contents:

The palladium-catalyzed reaction of aryl halides and allylic alcs. was an attractive method for obtaining α,β-unsaturated aldehydes and ketones, which represent key intermediates in organic synthesis. In this context, a 1,2,3-triazol-5-ylidene (aNHC)-based palladium(II) complex formed in situ was found to be a selective catalyst for the syntheses of building blocks from the corresponding aryl halides and allylic alcs., with yields ranging from 50% to 90%. The lack of toxic effects of the ligand precursor (1,2,3-triazolium salt) of the palladium(II) complex for the harpacticoid copepod Amphiascoides atopus allowed to contrast the efficiency of the catalytic system with the potential impact of the principal waste chem. in global aquatic ecosystems, which has not been previously addressed. In the experiment, the researchers used 2-Bromobenzonitrile(cas: 2042-37-7Synthetic Route of C7H4BrN)

A series of twenty-six compounds of furfuryl or benzyl tetrahydropyrazino[1,2-a]indole analogs were synthesized and evaluated for cytotoxic activity against the estrogen receptor (ER)-pos. breast cancer cell line (MCF-7) and the epidermal growth factor receptor (EGFR) over-expressed triple-neg. breast cancer cell line (MDA-MB-468). Among them, compounds 2b, 2f and 2i showed more potent activity and selectivity against MDA-MB-468 cells than gefitinib, as an EGFR- tyrosine kinase inhibitor.
