Using com. available flow reactors, di(hetero)arylmagnesium and di(hetero)arylzinc reagents containing normally incompatible functional groups such as azides, nitro groups, isothiocyanates, esters, and ketones were generated in situ by lithium-metal exchange reactions of aryl bromides or iodides such as 1-azido-4-iodobenzene with BuLi or PhLi and transmetalation with either MgCl2·LiCl or ZnCl2. Reaction of the di(hetero)arylmagnesium and di(hetero)arylzinc reagents with electrophiles such as allyl bromide, cyclopropanecarbonyl chloride, and cyclopropyl 4-fluorophenyl ketone mediated by CuCN·2 LiCl or palladium-catalyzed coupling reactions yielded (hetero)arene-containing products such as 4-N3C6H4CH2CH:CH2 in 62-85% yields.

In 2019,Journal of the American Chemical Society included an article by Ghosh, Chandrani; Kim, Suyeon; Mena, Matthew R.; Kim, Jun-Hyeong; Pal, Raja; Rock, Christopher L.; Groy, Thomas L.; Baik, Mu-Hyun; Trovitch, Ryan J.. Formula: C7H4FN. The article was titled 《Efficient Cobalt Catalyst for Ambient-Temperature Nitrile Dihydroboration, the Elucidation of a Chelate-Assisted Borylation Mechanism, and a New Synthetic Route to Amides》. The information in the text is summarized as follows:

N,N-Diborylamines have emerged as promising reagents in organic synthesis; however, their efficient preparation and full synthetic utility have yet to be realized. To address both shortcomings, an effective catalyst for nitrile dihydroboration was sought. Heating CoCl2 in the presence of PyEtPDI afforded the six-coordinate Co(II) salt, [(PyEtPDI)CoCl][Cl]. Upon adding 2 equiv of NaEt3BH, hydride transfer to one chelate imine functionality was observed, giving (κ4-N,N,N,N-PyEtIPCHMeNEtPy)Co. Single-crystal x-ray diffraction and d. functional theory calculations revealed that this compound possesses a low-spin Co(II) ground state featuring antiferromagnetic coupling to a singly reduced imino(pyridine) moiety. Importantly, (κ4-N,N,N,N-PyEtIPCHMeNEtPy)Co was found to catalyze the dihydroboration of nitriles using HBPin with turnover frequencies of up to 380 h-1 at ambient temperature Stoichiometric addition experiments revealed that HBPin adds across the Co-Namide bond to generate a hydride intermediate that can react with addnl. HBPin or nitriles. Computational evaluation of the reaction coordinate revealed that the B-H addition and nitrile insertion steps occur on the antiferromagnetically coupled triplet spin manifold. Formation of the borylimine intermediate occurs following BPin transfer from the borylated chelate arm to regenerate (κ4-N,N,N,N-PyEtIPCHMeNEtPy)Co. Borylimine reduction is in turn facile and follows the same ligand-assisted borylation pathway. The independent hydroboration of alkyl and aryl imines was also demonstrated at 25°. With N,N-diborylamines in hand, their addition to carboxylic acids allowed for the direct synthesis of amides at 120°, without the need for an exogenous coupling reagent. The experimental part of the paper was very detailed, including the reaction process of 4-Fluorobenzonitrile(cas: 1194-02-1Formula: C7H4FN)

The article was titled 《A Metallaphotoredox Strategy for the Cross-Electrophile Coupling of α-Chloro Carbonyls with Aryl Halides》. The information in the text is summarized as follows:

Here, we demonstrate that a metallaphotoredox-catalyzed cross-electrophile coupling mechanism provides a unified method for the α-arylation of diverse activated alkyl chlorides, including α-chloroketones, α-chloroesters, α-chloroamides, α-chlorocarboxylic acids, and benzylic chlorides. This strategy, which is effective for a wide variety of aryl bromide coupling partners, is predicated upon a halogen atom abstraction/nickel radical-capture mechanism that is generically successful across an extensive range of carbonyl substrates. The construction and use of arylacetic acid products have further enabled two-step protocols for the delivery of valuable building blocks for medicinal chem., such as aryldifluoromethyl and diarylmethane motifs.

C.. Electric Literature of C7H4BrN And the article was included in Journal of the American Chemical Society in 2020. The article conveys some information:

The combined use of reaction kinetic anal., ultrafast spectroscopy, and stoichiometric organometallic studies has enabled the elucidation of the mechanistic underpinnings to a photocatalytic C-N cross-coupling reaction. Steady-state and ultrafast spectroscopic techniques were used to track the excited-state evolution of the employed iridium photocatalyst, determine the resting states of both iridium and nickel catalysts, and uncover the photochem. mechanism for reductive activation of the nickel cocatalyst. Stoichiometric organometallic studies along with a comprehensive kinetic study of the reaction, including rate-driving force anal., unveiled the crucial role of photocatalysis in both initiating and sustaining a Ni(I)/Ni(III) cross-coupling mechanism. The insights gleaned from this study further enabled the discovery of a new photocatalyst providing a >30-fold rate increase.

The development of novel fluorescent polymers has attracted significant attention owing to their potential applications in energy and environmental sciences. This study reports novel oligomer (TRZBT) synthesis via Wittig-Horner reaction using bithiophene aldehyde and triazine tri-Et phosphite. The resulting oligomer possesses large porous morphol., which was confirmed using SEM anal. Further, the chem. structure of TRZBT was confirmed by FT-IR, NMR, and GPC studies. The triazine acceptor (A) unit linked with bithiophene donor (D) unit through olefin π-conjugation resulted in a Donor-π-Acceptor (D-π-A) type oligomer. Detailed studies of the solvent-dependent photophys. properties of TRZBT were performed. Due to the alternate D-A structure of oligomer, enhanced intramol. charge transfer (ICT) properties between D and A moiety was observed Further, TRZBT in THF and THF: H2O (10:90) system effectively detected nitro-explosives in aqueous media, which exhibited high sensitivity, selectivity, and quick response via fluorescence quenching. TRZBT showed a higher quenching constant (Ksv) value of 4.91 x 105 M-1 towards picric acid as compared with other nitroaroms. Significantly, the detection limit of 1.58 nM in a 100% aqueous medium confirms that the synthesized material can detect even trace levels of the analyte.

Vascular endothelial growth factor-2 (VEGFR-2) plays a pivotal role in tumor angiogenesis. Herein, a library of novel 2-(4-(1H-indazol-6-yl)-1H-pyrazol-1-yl)acetamide derivatives were designed and synthesized as VEGFR-2 inhibitors based on scaffold hopping strategy. These compounds exhibited excellent inhibitory activity in both VEGFR-2 and tumor cell proliferation. Especially, compound I possessed potent VEGFR-2 inhibition with IC50 = 1.6 nM and anti-proliferation against HGC-27 tumor cells with IC50 = 0.36 +/- 0.11μM, as well as less toxicity against normal GES-1 cells with IC50 = 187.46 +/- 10.13μM. Moreover, I obviously inhibited colony formation, migration and invasion of HGC-27 cells by adjusting the expression of MMP-9 and E-cadherin, and induced HGC-27 cells apoptosis by increasing ROS production and regulates the expression of apoptotic proteins. Furthermore, I blocked the PI3K-Akt-mTOR signaling pathway in HGC-27 cells. In addition, anti-angiogenesis of I was proved by inhibition tube formation and the expression of p-VEGFR-2 in HUVEC cells. All the results demonstrated that I could be developed as a promising anticancer agent for gastric cancer therapy.
