Jadhav, Chetan; Nipate, Amol; Chate, Asha; Gill, Charansingh published their research in ACS Omega in 2021. The article was titled 《Triethylammonium Hydrogen Sulfate [Et3NH][HSO4]-Catalyzed Rapid and Efficient Multicomponent Synthesis of Pyrido[2,3-d]pyrimidine and Pyrazolo[3,4-b]pyridine Hybrids》.Application In Synthesis of 3-Oxo-3-phenylpropanenitrile The article contains the following contents:

An operationally simple, one-pot multicomponent reaction was developed for the assembly of pyrido[2,3-d]pyrimidine and pyrazolo[3,4-b]pyridine derivatives I [R1 = 4-ClC6H5, 2-OHC6H5, 4-BrC6H5; R2 = C6H5, 4-Cl-C6H5, etc], II [R1 = 4-ClC6H5, 4-MeC6H5 , 4-BrC6H5; R2 = C6H5, 4-ClC6H5; R3 = R4 = H, Me, etc], III [R1 = 4-ClC6H5, 4-MeC6H5; R2 = C6H5; R5 = NH2, etc] in excellent yields (92-94%) with high purity. The reactions were easy to perform simply by mixing of electron-rich amino heterocycles (including aminouracils and aminopyrazoles), aldehyde, and acyl acetonitrile in the presence of [Et3NH][HSO4] under solvent-free conditions. The remarkable feature of the present approach was that the ionic liquid possesses dual solvent-catalytic engineering capability. Results of this study revealed that 1 mmol of the ionic liquid catalyst under solvent-free conditions at 60°C is the best reaction parameter for the construction of fused pyridine and pyrimidine derivatives I, II and III in excellent yields. The present methodol. showed good results under gram-scale conditions, thereby indicating its applicability in industrial as well as academic settings in the near future.

Four new M3L2 mol. cages (CA1-CA4) were synthesized in excellent yield via coordination driven self -assembly of flexible tri-imidazole donors based on imidazolylphenyltriazine (L1) and imidazolylphenylbenzene (L2) cores with 90° cis-blocked (tetramethylethylenediamine or bis(diphenylphosphino)ferrocene) metal acceptors of Pd(II). Two of them CA1 and CA2 are highly soluble in H2O. All the cages were characterized by spectroscopic studies and ESI-MS; CA3 and CA4 also by x-ray diffraction. Selective formation of cages CA3 and CA4 was noticed instead of a hetero-ligand cage, when the metal acceptor (dppf)Pd(OTf)2 was treated with a mixture of ligands L1 and L2.4-Cyanobenzyl bromide(cas: 17201-43-3Quality Control of 4-Cyanobenzyl bromide) was used in this study.

《Nickel-Catalyzed Cyanation of Aryl Halides and Hydrocyanation of Alkynes via C-CN Bond Cleavage and Cyano Transfer》 was written by Chen, Hui; Sun, Shuhao; Liu, Yahu A.; Liao, Xuebin. Reference of 4-Bromobenzonitrile And the article was included in ACS Catalysis in 2020. The article conveys some information:

We report nickel-catalyzed cyanation and hydrocyanation methods to prepare aryl nitriles and vinyl nitriles from aryl halides and alkynes, resp. Using inexpensive and nontoxic 4-cyanopyridine N-oxide as the cyano shuttle, the methods provide an efficient approach to prepare aryl cyanides and vinyl nitriles under mild and operationally simple reaction conditions with a broad range of functional group tolerances. In hydrocyanation of alkynes, the method demonstrated good regioselectivity, producing predominantly E- or Z-alkenyl nitriles in a controlled manner and exclusively Markovnikov vinyl nitriles when internal diaryl alkynes and terminal alkynes were applied as the substrates, resp. The preliminary mechanistic investigation indicated that the C-CN bond cleavage process is promoted by oxidative addition to the nickel(I) complex in the cyanation of aryl halides, and further studies via a series of deuterium exchange experiments indicated that water serves as the hydrogen source for the hydrocyanation of alkynes. In the experiment, the researchers used many compounds, for example, 4-Bromobenzonitrile(cas: 623-00-7Reference of 4-Bromobenzonitrile)

4-Bromobenzonitrile(cas: 623-00-7) has been used in the synthesis of 4-iodobenzonitrile via photo-induced aromatic Finkelstein iodination reaction.Reference of 4-Bromobenzonitrile 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.
