The article was written by Zhu, Chen; Kale, Ajit Prabhakar; Yue, Huifeng; Rueping, Magnus. The article contains the following contents:

A nickel-catalyzed cross-coupling amination of aryl halides/aryl tosylates with weak nitrogen nucleophiles including anilines, sulfonamides, sulfoximines, carbamates and imines via concerted paired electrolysis was described to provide substituted amines Ar1NHAr2 [Ar1 = 4-MeC6H4, 4-NCC6H4, 4-tBuC6H4, etc.; Ar2 = Ph, 2-naphthyl, 4-MeC6H4, etc.] and aryl sulfonamides Ar3NRSO2R1 [Ar3 = 2-MeC6H4, 4-NCC6H4, 4-tBuC6H4, etc.; R = H, Me R1 = Me, Bn, 4-MeC6H4, etc.]. Notably, electron-deficient anilines and sulfonamides were also suitable substrates. Interestingly, when benzophenone imine was applied in the arylation, the product selectivity toward the formation of amine and imine product could be addressed by a base switch. In addition, the a.c. mode could be successfully applied. DFT calculations supported a facilitated reductive elimination pathway. In the experiment, the researchers used 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Synthetic Route of C7H3BrFN)

SDS of cas: 99902-72-4 And the article was included in Synlett on August 31 ,2017. The article conveys some information:

Unsym. di(heteroaryl) ethers were synthesized by the rhodium-catalyzed heteroaryl exchange reaction of heteroaryl aryl ethers and heteroaryl esters at equilibrium [e.g., 2-phenoxybenzothiazole + 3-pyridyl benzoate → 2-(3-pyridyloxy)benzothiazole + Ph benzoate]. Diverse unsym. di(heteroaryl) ethers containing five- and six-membered heteroarenes were obtained. Di(heteroaryl) ethers can be synthesized starting from diaryl ethers, because heteroaryl aryl ethers are obtained by the heteroaryl exchange reaction of diaryl ethers. In the experiment, the researchers used many compounds, for example, 6-Phenoxynicotinonitrile(cas: 99902-72-4SDS of cas: 99902-72-4)

6-Phenoxynicotinonitrile(cas: 99902-72-4) belongs to nitriles. Nitriles are found in many useful compounds.

In 2019,Synthesis included an article by Greve, Eric; Porter, Jacob D.; Dockendorff, Chris. Computed Properties of C8H6BrN. The article was titled 《DFT-Assisted Design and Evaluation of Bifunctional Amine/Pyridine-Oxazoline Metal Catalysts for Additions of Ketones to Unactivated Alkenes and Alkynes》. The information in the text is summarized as follows:

Bifunctional catalyst systems for the direct addition of ketones to unactivated alkenes/alkynes were designed and modeled by d. functional theory (DFT). The designed catalysts possess bidentate ligands suitable for binding of pi-acidic Group 10 metals capable of activating alkenes/alkynes, and a tethered organocatalyst amine to activate the ketone via formation of a nucleophilic enamine intermediate. The structures of the designed catalysts before and after C-C bond formation were optimized using DFT, and reaction steps involving Group 10 metals were predicted to be significantly exergonic. A novel oxazoline precatalyst with a tethered amine separated by a meta-substituted benzene spacer was synthesized via a 10-step sequence that includes a key regioselective epoxide ring-opening step. It was combined with Group 10 metal salts, including cationic Pd(II) and Pt(II), and screened for the direct addition of ketones to several alkenes and an internal alkyne. 1H NMR studies suggest that catalyst-catalyst interactions with this system via amine-metal coordination may preclude the desired addition reactions. The catalyst design approach disclosed here, and the promising calculations obtained with square planar Group 10 metals, light a path for the discovery of novel bifunctional catalysts for C-C bond formation. In addition to this study using 2-(3-Bromophenyl)acetonitrile, there are many other studies that have used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Computed Properties of C8H6BrN) was used in this study.
