Fu, Zhengqiang published the artcileManganese Catalyzed Direct Amidation of Esters with Amines, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is amide preparation; ester amine amidation manganese catalyst.

The transition metal catalyzed amide bond forming reaction of esters with amines has been developed as an advanced approach for overcoming the shortcomings of traditional methods. The broad scope of substrates in transition metal catalyzed amidations remains a challenge. Here, a manganese(I)-catalyzed method for the direct synthesis of amides from a various number of esters and amines is reported with unprecedented substrate scope using a low catalyst loading. A wide range of aromatic, aliphatic, and heterocyclic esters, even in fatty acid esters, reacted with a diverse range of primary aryl amines, primary alkyl amines, and secondary alkyl amines to form amides. It is noteworthy that this approach provides the first example of the transition metal catalyzed amide bond forming reaction from fatty acid esters and amines. The acid-base mechanism for the manganese(I)-catalyzed direct amidation of esters with amines was elucidated by DFT calculations

A terphenyl phosphine ligand (2,6-bis(2,4,6-triisopropylphenyl)phenyl-dicyclohexylphosphine, TXPhos) and its supported palladium complex [(TXPhos)(allyl)PdCl] have been developed and the catalyst system is highly efficient in amination of aryl halides ArX (Ar = Ph, 2-methoxyphenyl, 4-cyanophenyl, etc.; X = Cl, Br, I) with 1° anilines RNH2 (R = Ph, 2-nitrophenyl, 2,5-dimethylphenyl, etc.), especially effective for densely functionalized substrates including both partners possessing ortho-ester, acetyl, nitrile and nitro groups. With the TXPhos-supported catalyst system, many partner combinations have been unprecedentedly realized and the base scope has been even extended to KOAc, which is even the best choice in the amination of 2-nitrochlorobenzene.

Vijeta, Arjun published the artcileAn Integrated Carbon Nitride-Nickel Photocatalyst for the Amination of Aryl Halides Using Sodium Azide, Computed Properties of 1885-29-6, the main research area is primary aniline preparation; haloarene sodium azide amination integrated carbon nitride nickel photocatalyst; Carbon Nitride; Green Chemistry; Heterogeneous Catalysis; Organic Synthesis; Photocatalysis.

A photocatalytic protocol for the selective synthesis of primary anilines RNH2 [R = Ph, 4-BrC6H4, 3-pyridyl, etc.] via cross-coupling of a wide range of aryl/heteroaryl halides with sodium azide using a photocatalyst powder consisting of nickel(II) deposited on mesoporous carbon nitride (Ni-mpg-CNx) was reported. This heterogeneous photocatalyst contained a high surface area with a visible light-absorbing and adaptive “”built-in”” solid-state ligand for the integrated catalytic Ni site. The method displayed a high functional group tolerance, required mild reaction conditions, and benefited from easy recovery and reuse of the photocatalyst powder. Thereby, it overcame the need of complex ligand scaffolds required in homogeneous catalysis, precious metals and elevated temperatures/pressures in existing protocols of primary anilines synthesis. The reported heterogeneous Ni-mpg-CNx held potential for applications in the academic and industrial synthesis of anilines and exploration of other photocatalytic transformations.

Gillespie, James E. published the artcileRegioselective Radical Arene Amination for the Concise Synthesis of ortho-Phenylenediamines, COA of Formula: C7H6N2, the main research area is ortho phenylenediamine preparation regioselective radical arene amination; monoalkyl amine benzimidazole benzotriazole preparation; anionic substrate radical cation regioselective radical amination.

The formation of arene C-N bonds directly from C-H bonds is of great importance and there has been rapid recent development of methods for achieving this through radical mechanisms, often involving reactive N-centered radicals. A major challenge associated with these advances is that of regiocontrol, with mixtures of regioisomeric products obtained in most protocols, limiting broader utility. We have designed a system that utilizes attractive noncovalent interactions between an anionic substrate and an incoming radical cation in order to guide the latter to the arene ortho position. The anionic substrate takes the form of a sulfamate-protected aniline and telescoped cleavage of the sulfamate group after amination leads directly to ortho-phenylenediamines, key building blocks for a range of medicinally relevant diazoles. Our method can deliver both free amines and monoalkyl amines allowing access to unsym., selectively monoalkylated benzimidazoles and benzotriazoles. As well as providing concise access to valuable ortho-phenylenediamines, this work demonstrates the potential for utilizing noncovalent interactions to control positional selectivity in radical reactions.

Four amine derivative compounds were synthesized: 2-[(phenylamino)methyl]phenol, 2-{[(4-hydroxyphenyl)amino]methyl}phenol, 2-[(2-hydroxybenzyl)amino]benzonitrile and 2-{[(3-chlorophenyl)amino]methyl}phenol. The structure of the organic mols. was confirmed by FT-IR, 13C NMR and 1H NMR spectroscopy analyses. Their corrosion inhibition performances on mild steel in 1 M HCl were investigated using electrochem. measurements and surface anal. SEM anal. confirms the presence on the mild steel surface of a protective film of the as-prepared organic compounds, which depends on the substituent groups. Moreover, d. functional theory and mol. dynamics simulation were employed in order to determine the adsorption mechanism and the position of amine derivative mols. towards the mild steel surface in an aggressive solution and to confirm the electrochem. results. The inhibition efficiency (IE) decreases with a decrease in concentration and the adsorption obeyed the Langmuir isotherm. The substitution of the OH group on the aromatic ring by Cl or CN increases IE to 90.23 and 92.56%, resp.

Mu, Xueli published the artcileHow and Why a Protic Ionic Liquid Efficiently Catalyzes Chemical Fixation of CO2 to Quinazoline-2,4-(1H,3H)-diones: Electrostatically Controlled Reactivity, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is aminobenzonitrile carbon dioxide cyclization protic IL catalyst quinazolinedione formation.

A d. functional theory study has been conducted to gain insight into the intriguing exptl. observations on the synthesis of quinazoline-2,4-(1H,3H)-diones from 2-aminobenzonitriles reacting with CO2 catalyzed by protic ionic liquids (ILs). We explored the mol. mechanism of the titled reaction, as well as the origin and catalytic nature of different ILs toward the reaction in detail. The calculated energetically viable mechanism involves CO2 attack, intramol. rearrangement, and intramol. cyclization stages. This mechanism features the initial polarization of the CN triple bond with the assistance of the real catalytic species, [HDBU+][TFECOO-], where the cation [HDBU+] acts as Bronsted acid and the anion [TFECOO-], the adduct of anion [TFE-] and CO2, acts as a nucleophile. The calculated results present the electrostatically controlled character of the reaction, where the reactivity relies on the electrostatic interaction of the IL cation with the anion. The reactivity can be controlled and regulated by the basicity of the deprotonated counterpart of the IL cation as well as the CO2 adsorption ability of the IL anion. The best catalytic performance of [HDBU+][TFE-] is attributed to its strongest basicity of the deprotonated counterpart of [HDBU+] and its most efficient CO2 adsorption property of [TFE-]. These theor. results are expected to provide guidance for designing efficient IL-based catalysts in preparing quinazoline-2,4-(1H,3H)-diones by reacting 2-aminobenzonitriles with CO2.

Li, Shasha published the artcileA nanoscale observation to explain the discrepancy of electron exchange capacities between biochar containing comparable surface redox-active moieties, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is biochar nanoscale electron exchange capacity surface redox active moiety.

Biochar, possessing electron exchange capacities (EEC), is generally involved in environmental redox reactions due to the presence of redox-active moieties (RAMs). The phenomenon that chars containing comparable RAMs possess differential EEC revealed that the accessibility of RAMs is important to the redox properties. However, many studies have focused on the type of RAMs, whereas the distribution has been insufficiently investigated. Herein, we achieved nanoscale observation of electroactive moieties on the surface of six chars using a conductive at. force microscope. For the two specific kinds of chars with submicron particles and opposite current distributions, the submicron particles took up only 1-4%wt of biochar accounting for approx. 30-50% of electron-donating capacity (EDC), and electron-accepting capacity (EAC) became 87% and 1.40 times as before after removing submicron particles, resp. Meanwhile, the combined impact of RAMs and surface topog. (that uneven distribution of RAMs resulted in outstanding EEC by enhancing accessibility) was clarified. Furthermore, direct evidence of the link between char structure and EEC (that condensed aromatic structures were indispensable to EAC while both heteroatoms and amorphous aromatics contributed to EDC) was established. These findings can aid in understanding the functions of biochar in biotic and abiotic redox processes.

Tarawneh, Amer H. published the artcileA new and convenient synthetic method for 4-aminoquinoline-3-carbonitrile and its derivatives, Synthetic Route of 1885-29-6, the main research area is aminoquinoline carbonitrile preparation; cyanoethylamino benzonitrile preparation chemoselective Thorpe Ziegler cyclization; anthranilonitrile bromopropanenitrile monoalkylation.

A convenient approach is described for the general synthesis of 4-aminoquinoline-3-carbonitrile I [R = H, 6-Me, 7-Me, 6-F] scaffolds. A series of substituted anthranilonitriles RC6H3(2-CN)NH2 [R = H, 4-Me, 5-Me, 5-F] bearing electron-donating and-withdrawing groups on the arene reacts with 3-bromopropanenitrile and t-BuOK in anhydrous DMF at ca. 24°C. A wide variety of bases have been used to optimize selective mono-N-alkylation. The best conditions lead to the corresponding 2-(cyanoethylamino)benzonitriles RC6H3(2-CN)NH(CH2)2CN in moderate or good yields. Thorpe-Ziegler cyclization of the N-unprotected 2-(cyanoethylamino)benzonitrile analogs with t-BuLi in THF at -78°C gives I in moderate yields. Owing to their vicinal amino and cyano functional groups that can function as enaminonitrile moieties, 4-aminoquinoline-3-carbonitriles I are attractive building blocks frequently used in ring construction.
