Iron- and copper-based bifunctional catalysts for the base- and solvent-free C-N coupling of amines and aryl/benzyl chlorides under aerobic conditions was written by Sharma, Charu;Srivastava, Avinash K.;Sharma, Deepak;Joshi, Raj K.. And the article was included in New Journal of Chemistry in 2022.Recommanded Product: 4-(Benzylamino)benzonitrile This article mentions the following:

The iron chalcogenide carbonyl cluster Fe₃Se₂(CO)₉ and Cu(OAc)₂ were found to be outstanding bimetallic catalysts for the C-N coupling reaction of amines and aryl chlorides. The reaction proceeded under base- and solvent-free conditions at 100°C to produce excellent transformations of N-arylated products in just 4 h. The method worked equally well for all the possible variants of amines, including aliphatic, aromatic and benzylic amine. The present C-N coupling method was highly economical, strongly feasible and showed excellent competence with electron-withdrawing and base-sensitive functionalities. Moreover, it was the first report in which a zero-valent iron complex was explored for C-N coupling reaction. In the experiment, the researchers used many compounds, for example, 4-(Benzylamino)benzonitrile (cas: 10282-32-3Recommanded Product: 4-(Benzylamino)benzonitrile).

4-(Benzylamino)benzonitrile (cas: 10282-32-3) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Recommanded Product: 4-(Benzylamino)benzonitrile

The [2+2] cycloaddition vs. substitution in photochemical reactions of methoxybenzene-acrylonitrile systems was written by Ohashi, Mamoru;Tanaka, Yoshio;Yamada, Shuzo. And the article was included in Tetrahedron Letters in 1977.SDS of cas: 5351-07-5 This article mentions the following:

Irradiation of PhOMe and RCH:CR¹CN (I; R, R¹ = H, Me) in MeCN gave the corresponding [2+2]cycloadducts II, whereas irradiation of PhOMe and I (R, R¹ = H, Me) in MeOH gave substitution products in addition to II. Thus the photochem. reactions of I (R, R¹ = H, Me) with PhOMe in MeCN are similar to those of I (R = R¹ = H) with PhOMe in MeCN (O. et al., 1976) whereas the reactions in MeOH differ, since I (R = R¹ = H) gave only substitution products, the amount decreasing in the order I (R = R¹ = H) > I (R = H, R¹ = Me) > I (R = Me, R¹ = H). A similar tendency is also observed for (MeO)₂C₆H₄-RCH:CR¹CN systems. The higher the reduction potential (or electron affinity) of the olefin or the lower the oxidation potential of the aromatic, the larger the amount of substitution products. Although participation of the proton-transfer step is revealed by the use of MeOD in place of MeOH, the rate-determining step of the substitution is electron transfer. A reaction scheme consistent with these results is given. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5SDS of cas: 5351-07-5).

2-(4-Methoxyphenyl)-2-methylpropanenitrile (cas: 5351-07-5) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.SDS of cas: 5351-07-5

A simple and sensitive intramolecular charge transfer fluorescent probe to detect CN^– in aqueous media and living cells was written by Shahid, Mohammad;Misra, Arvind. And the article was included in Analytical Methods in 2013.Related Products of 55490-87-4 This article mentions the following:

The optical behavior of a simple intramol. charge transfer (ICT) fluorescent probe 1 has been described to detect cyanide (CN^–) selectively for the first time in solution and living cells. The strong emission displayed by 1 is attributed to a decrease in ICT from anthracene to dicyanovinyl group. The change in color of the solution was visible to the naked eye. Probe 1 forms a 1:1 adduct with CN^– with detection limit of 26 ppb. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4Related Products of 55490-87-4).

And the article was included in Medicinal Chemistry Research in 1999.Electric Literature of C8H6N2O2 This article mentions the following:

A classical folate analog inhibitor of dihydrofolate reductase is described. This compound, 4′-methylene-5,8,10-trideazaaminopterin [Mobiletrex; M-Trex], is resistant to both polyglutamylation and aldehyde oxidase mediated 7-hydroxylation. Mobiletrex exhibited excellent inhibition of human dihydrofolate reductase and inhibited growth of a number of human tumor cells in culture. Unlike methotrexate, mobiletrex was not a substrate of either folylpolyglutamate synthetase or rabbit liver aldehyde oxidase. Mobiletrex caused total growth inhibition (TGI) of a number of human tumor cells at therapeutically relevant concentrations (âˆ?1×10^-6 M) which are potencies strikingly higher than those of methotrexate. In the experiment, the researchers used many compounds, for example, 5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6Electric Literature of C8H6N2O2).

5-Methyl-2-nitrobenzonitrile (cas: 64113-86-6) belongs to nitriles.

Alkyl nitriles are sufficiently acidic to undergo deprotonation of the C-H bond adjacent to the CN group.Strong bases are required, such as lithium diisopropylamide and butyl lithium. The product is referred to as a nitrile anion. Electric Literature of C8H6N2O2
