Name: 4-Cyanobenzyl bromideIn 2019 ,《Catalyst-Free Sulfonylation of (Hetero)aryl Iodides with Sodium Dithionite》 was published in Advanced Synthesis & Catalysis. The article was written by Li, Yuewen; Liu, Tong; Qiu, Guanyinsheng; Wu, Jie. The article contains the following contents:

The com. available and cheap sodium dithionite was used as the source of sulfonyl group for the synthesis of heteroaryl-sulfones I [R = n-Pr, Ph, 4-MeC6H4, etc.; R1 = 2-thienyl, 2-pyridyl, 2-pyrimidinyl, etc.] and sulfonamides II [R2 = Et, Ph; R3 = Me, Et; R2R3 = (CH2)4, (CH2)2O(CH2)2, (CH2)2S(CH2)2] from heteroaryl-iodides under catalyst-free conditions. During the reaction process, sodium sulfinates generated in situ were the key intermediate, which further converted into heteroaryl-sulfones I and sulfonamides II by treating with bromoalkanes and amines resp. This transformation proceeded through a radical process initiated by sodium dithionite, providing a convenient route to sulfonyl-containing compounds The experimental process involved the reaction of 4-Cyanobenzyl bromide(cas: 17201-43-3Name: 4-Cyanobenzyl bromide)

4-Cyanobenzyl bromide(cas: 17201-43-3) can reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile. And it may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.Name: 4-Cyanobenzyl bromide

《Green synthesis of zirconium phosphate by combustion method: photocatalytic application and microwave-assisted catalytic conversion of aldehyde to nitriles》 was written by Shashank, M.; Bhojya Naik, H. S.; Shashikanth, J.; Nizam, Aatika; Nagaraju, G.. Electric Literature of C7H4BrNThis research focused onzirconium phosphate nanoparticle photocatalytic degradation. The article conveys some information:

Water pollution has increased swiftly, especially the dyes from industries that have disturbed aquatic eco-system. Photocatalytic degradation (PCD) is one of the attractive methods to eliminate dyes from industrial effluents. Zirconium phosphate (ZP) nanoparticles were synthesized by combustion method using zirconyl nitrate and phosphorous pentoxide as precursors. The obtained ZP was characterized by powder X-ray diffractogram, Fourier transform IR, SEM, high-resolution transmission electron microscopy, Raman spectroscopy, photoluminescence spectroscopy, Brunauer-Emmett-Teller surface area. PCD was carried out using methylene blue as a model pollutant in aqueous medium in the presence of UV light irradiation with different concentrations of dye, catalyst and pH. Higher degradation efficiency was observed in basic medium. ZP is employed as a catalyst to form nitrides from aldehydes using different solvents with different aldehydes.

The experimental part of the paper was very detailed, including the reaction process of 2-Bromobenzonitrile(cas: 2042-37-7Electric Literature of C7H4BrN)

2-Bromobenzonitrile(cas: 2042-37-7) belongs to a group of ortho-substituted bromobenzenes that have varying hepatotoxicity effects in the presence of rat liver microsomes in vitro. 2-Bromobenzonitrile is also used as a starting material to synthesize novel benzothiophene derivatives that were found to exhibit antibacterial and antifungal activity.Electric Literature of C7H4BrN

Boltalina, Olga V.; Markov, Vitaliy Y.; Borschevskii, Andrey Y.; Davydov, Vladimir Y.; Sidorov, Lev N.; Bezmelnitsin, Valery N.; Eletskii, Alexander V.; Taylor, Roger published an article in Mendeleev Communications. The title of the article was 《Saturated vapor pressure and enthalpy of sublimation of C84》.Name: 3-Chloro-4-fluorophenylacetonitrile The author mentioned the following in the article:

The vapor pressure and sublimation enthalpy of HPLC-purified C84 have been determined by Knudsen cell mass spectrometry in the temperature range 658-980 K; the temperature-pressure equation is ln(p/Pa) = (-24337 ± 539)/(T/K) + (25.15 ± 0.64), the mean sublimation enthalpy at 853 K is 202 ± 4 kJ mol-1. After reading the article, we found that the author used 3-Chloro-4-fluorophenylacetonitrile(cas: 658-98-0Name: 3-Chloro-4-fluorophenylacetonitrile)

3-Chloro-4-fluorophenylacetonitrile(cas: 658-98-0) belongs to nitriles. Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.Name: 3-Chloro-4-fluorophenylacetonitrile

3-Chloro-1H-indole-2-carbonitrile(cas: 74960-46-6) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Electric Literature of C9H5ClN2
