An iron(0) complex bearing a cyclopentadienone ligand catalyzed N-methylation and N-ethylation of aryl and aliphatic amines with methanol or ethanol in mild and basic conditions through a hydrogen autotransfer borrowing process is reported. A broad range of aromatic and aliphatic amines underwent mono- or dimethylation in high yields. DFT calculations suggest mol. hydrogen acts not only as a reducing agent but also as an additive to displace thermodn. equilibrium In the experiment, the researchers used many compounds, for example, 4-(Ethylamino)benzonitrile (cas: 4714-63-0Product Details of 4714-63-0).

4-(Ethylamino)benzonitrile (cas: 4714-63-0) belongs to nitriles. The R-C-N bond angle in and nitrile is 180° which give a nitrile functional group a linear shape. Both the carbon and the nitrogen are sp hydridized which leaves them both with two p orbitals which overlap to form the two π bond in the triple bond. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Product Details of 4714-63-0

A simple triazine (D-A) based organic fluorophore selective dual sensor for Copper(II) and dichromate ions and its solvatochromism, solid state sensing, logic gate applications was written by Harikrishnan, Muniyasamy;Sadhasivam, Velu;Mariyappan, Mathappan;Murugesan, Sepperumal;Malini, Nelson;Siva, Ayyanar. And the article was included in Dyes and Pigments in 2019.Name: 4-(Ethylamino)benzonitrile This article mentions the following:

Herein, the design and synthesis of triazine based fluorophore for selective dual sensing of copper(II) and dichromate ions in non-aqueous solution has been reported. The triazine based fluorophore (TZAS) was synthesized in very good yield from inexpensive starting materials. The fluorophore has been thoroughly characterized by various spectral techniques. The TZAS has N-(ethyl)amine and triazine core which are acting as donor and acceptor, resp. Further, its interaction with various analytes in both solid and solution phases are studied. The TZAS compound shows pos. solvatochromism upon increasing the solvent polarity from non-polar to polar solvent. The sensing ability of TZAS has been studied against various analytes (cations and anions). The results indicated that the detection limits for dichromate and copper ions in dimethylsulfoxide solvent medium are 1.3 × 10^-8 M and 11 × 10^-8 M resp. The sensing mechanism of the proposed probe in the presence of the Cu²⁺/Cr₂O^2-₇ were determined by the support of NMR, ESI-MS, FTIR spectra, Job’s plot and d. functional theory. Furthermore, the energy gap between frontier orbitals of TZAS and TZAS-analyte calculated through theor. (DFT) anal. The sensing performance of the TZAS is also examined in a logic circuit. This is the first dual coupled sensor of copper(II) cation and dichromate anion by organic fluorophore material. In the experiment, the researchers used many compounds, for example, 4-(Ethylamino)benzonitrile (cas: 4714-63-0Name: 4-(Ethylamino)benzonitrile).

4-(Ethylamino)benzonitrile (cas: 4714-63-0) belongs to nitriles. The electronic structure of nitriles is very similar to that of an alkyne with the main difference being the presence of a set of lone pair electrons on the nitrogen. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).Name: 4-(Ethylamino)benzonitrile
