The Knoevenagel condensation of a series of substituted Ph acetonitriles with 1H-pyrrole-2-carbaldehyde was examined in seven 1-butyl-3-methylimidazolium based ionic liquids and three protic ionic liquids Of these [BMIM][Br] and [BMIM][OH], with catalytic piperidine, proved most efficient affording 3-substituted-(1H-pyrrol-2-yl)acrylonitriles 3-17 in good to excellent yields (98%) while utilization of the protic ionic liquid Pr ammonium nitrate resulted in reduced yields (0-66%). Screening of the 3-substituted-(1H-pyrrol-2-yl)acrylonitriles analogs 3-17 against a panel of 11 cancer cell lines and one normal cell line allowed the identification of a series of compounds with broad spectrum cytotoxicity, but more interestingly a significant degree of MCF-7 breast cancer cell line specificity was evident with 6 (7 to >25 fold) and 13 (5.7 to >80 fold). Other analogs show high level of efficacy against specific cell lines with 10 showing excellent activity against MCF-7 (GI50 = 1.7 μM) and A431 (GI50 = 2.8 μM) cell lines. The most promising of the compounds identified herein were the 4-CF3 substituted 10 and the 3,4-dichloro substituted 13 with excellent activities against MCF-7 and A431 cell lines. The 3,4-dichloro-13 was a 0.56 μM potent inhibitor of MCF-7 cell growth. The results came from multiple reactions, including the reaction of 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Name: 2-(3-Bromophenyl)acetonitrile)

In 2018,Soft Matter included an article by Pocock, Emily E.; Mandle, Richard J.; Goodby, John W.. Name: 4-Bromo-2-fluorobenzonitrile. The article was titled 《Molecular shape as a means to control the incidence of the nanostructured twist bend phase》. The information in the text is summarized as follows:

Eleven novel materials I [R = 4-(4-CNC6H4)C6H4, 4-(3,4-di-FC6H4)C6H4, 4-(4-F5SC6H4)C6H4, etc.] with all found to exhibited the twist-bend phase and a linear relationship between TN-I and TTB-N were prepared and studied. A computational study of the conformational landscape revealed the octamethyleneoxy spacer to had a broader distribution of bend-angles than the nonamethylene equivalent, leading to reductions in the thermal stability of the TB phase. This result indicates that a tight distribution of bend-angles should stabilize the TB phase and lead to direct TB-Iso phase transitions, and conversely a broader distribution should destabilize the TB phase which may allowed new states of matter that were occluded by the incidence of this phase to be revealed. In the part of experimental materials, we found many familiar compounds, such as 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Name: 4-Bromo-2-fluorobenzonitrile)

《Photo-Ni-Dual-Catalytic C(sp2)-C(sp3) Cross-Coupling Reactions with Mesoporous Graphitic Carbon Nitride as a Heterogeneous Organic Semiconductor Photocatalyst》 was published in ACS Catalysis in 2020. These research results belong to Khamrai, Jagadish; Ghosh, Indrajit; Savateev, Aleksandr; Antonietti, Markus; Koenig, Burkhard. Application In Synthesis of 4-Bromobenzonitrile The article mentions the following:

The synergistic combination of a heterogeneous organic semiconductor mesoporous graphitic carbon nitride (mpg-CN) and a homogeneous nickel catalyst with visible-light irradiation at room temperature affords the C(sp2)-C(sp3) cross-coupling of aryl halides and potassium alkyl trifluoroborates by single electron transmetallation. Like the homogeneously catalyzed protocol, the reaction is compatible with a variety of functional groups including electron-donating and electron-withdrawing aryl and heteroaryl moieties. Moreover, this protocol allows the installation of allyl groups onto (hetero)arenes, enlarging the scope of the method. The heterogeneous mpg-CN photocatalyst is easily recovered from the reaction mixture and reused several times, paving the way for larger-scale industrial applications of this type of photocatalytic bond-forming reactions.

《Discovery and characterization of a novel perylenephotoreductant for the activation of aryl halides》 was written by Li, Min; Li, Jia; Guo, Baodang; Liu, Xuanzhong; Yuan, Zhenbo; Wu, Yawen; Yin, Huimin; Huang, Shuping; Zhang, Yan; Rao, Yijian. Related Products of 105942-08-3 And the article was included in Journal of Catalysis in 2021. The article conveys some information:

To develop a photocatalyst with catalytical activity for substrates with low reactivities is always highly desired. Herein, based on the principle of structure-property relationships, we rationally designed the natural product cercosporin, the naturally occurring perylenequinonoid pigment, to develop a novel organic perylenephotoreductant, hexacetyl reduced cercosporin (HARCP), through structural manipulation. Compared with cercosporin, HARCP shows prominent electrochem. and photophys. characteristics with greatly improved photoreductive activity, fluorescence lifetime and fluorescence quantum yield. These properties allowed HARCP as a powerful photoreductant to efficiently realize a series of benchmark reactions, including photoreduction, alkoxylation and hydroxylation to construct C-H and C-O bonds using aryl halides as substrates under mild conditions, all of which have never been achieved by the same photocatalyst. Thus, this study well supports the notion that the principle between structural manipulation and photocatalytic activity is of great significance to design customized photocatalysts for photoredox chem. The results came from multiple reactions, including the reaction of 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Related Products of 105942-08-3)

Zhou, Quan-Quan; Zou, You-Quan; Kar, Sayan; Diskin-Posner, Yael; Ben-David, Yehoshoa; Milstein, David published an article in 2021. The article was titled 《Manganese-Pincer-Catalyzed Nitrile Hydration, α-Deuteration and α-Deuterated Amide Formation via Metal Ligand Cooperation》, and you may find the article in ACS Catalysis.Related Products of 31938-07-5 The information in the text is summarized as follows:

A simple and efficient system for the hydration and α-deuteration of nitriles to form amides RC(O)NH2 [R = Me, Bn, 4-FC6H4, etc.] and α-deuterated nitriles R1CD2CN [R1 = PhCH2CH2, 3-MeC6H4, 3-pyridyl, etc.] catalyzed by a single pincer complex of the earth-abundant manganese capable of metal-ligand cooperation is reported. The deuteration reaction is selective and tolerates a wide range of functional groups, giving the corresponding amides in moderate to good yields. Changing the solvent from tert-butanol to toluene and using D2O results in formation of α-deuterated nitriles in high selectivity. Moreover, α-deuterated amides can be obtained in one step directly from nitriles and D2O in THF. Preliminary mechanistic studies suggest the transformations contributing toward activation of the nitriles via a metal-ligand cooperative pathway, generating the manganese ketimido and enamido pincer complexes as the key intermediates for further transformations.

In 2022,Wang, Qiao-Lin; Sun, Zhaozhao; Huang, Huawen; Mao, Guojiang; Deng, Guo-Jun published an article in Green Chemistry. The title of the article was 《Stoichiometric couplings of methylarenes through visible-light-induced bromo radical formation from aryl halides》.Application In Synthesis of 2-Bromobenzonitrile The author mentioned the following in the article:

A visible-light/nickel dual catalyzed stoichiometric coupling of methylarenes via bromine radical-enhanced HAT was developed. Aryl bromides serve as both cross-coupling partners and bromine radical precursors. Mechanistic studies revealed that the bromine radical acts as a highly efficient HAT reagent to abstract the benzylic C(sp3)-H bond to deliver a benzylic radical and subsequently engages in Ni-catalyzed arylation couplings. The synthetic utility of this approach was further proved by its application in the late-stage arylation or benzylation of several drug-like and complex mols. in a stoichiometric manner. In the experiment, the researchers used 2-Bromobenzonitrile(cas: 2042-37-7Application In Synthesis of 2-Bromobenzonitrile)
