Heard, David M.; Doobary, Sayad; Lennox, Alastair J. J. published the artcile< 3D Printed Reactionware for Synthetic Electrochemistry with Hydrogen Fluoride Reagents>, COA of Formula: C7H8BrN, the main research area is three dimensional printing electrochem hydrogen fluoride reagent.

Electrochem. fluorination reactions of organic compounds frequently employ hydrogen fluoride reagents that are corrosive. The corrosive nature of these reagents necessitates either the construction or purchase of cells that are stable to hydrogen fluoride, which require high-cost materials, machining time and expertise. Herein, we offer an alternative solution using 3D printing, which is an inexpensive and rapid manufacturing technique. We have designed, printed and shared four different cell types in polypropylene and tested them in an electrochem. alkene difluorination reaction in the presence of triethylamine. 3HF and pyridinium poly. (HF).

Zhang, Yangmin; Yang, Hanmin; Chi, Quan; Zhang, Zehui published the artcile< Nitrogen-Doped Carbon-Supported Nickel Nanoparticles: A Robust Catalyst to Bridge the Hydrogenation of Nitriles and the Reductive Amination of Carbonyl Compounds for the Synthesis of Primary Amines>, Safety of 4-Bromobenzylamine, the main research area is primary amine preparation; nitrogen doped carbon supported nickel nanoparticle catalyst preparation; nitrile aldehyde hydrogenation reductive amination; amines; hydrogenation; nickel; nitrogen-doped carbon; reductive amination.

An efficient method was developed for the synthesis of primary amines either from the hydrogenation of nitriles or reductive amination of carbonyl compounds The reactions were catalyzed by nitrogen-doped mesoporous carbon (MC)-supported nickel nanoparticles (abbreviated as MC/Ni). The MC/Ni catalyst demonstrated high catalytic activity for the hydrogenation of nitriles into primary amines in high yields (81.9-99 %) under mild reaction conditions (80° and 2.5 bar H2). The MC/Ni catalyst also promoted the reductive amination of carbonyl compounds for the synthesis of primary amines at 80° and 1 bar H2. The hydrogenation of nitriles and the reductive amination proceeded through the same intermediates for the generation of the primary amines. To the best of knowledge, no other heterogeneous non-noble metal catalysts have been reported for the synthesis of primary amines under mild conditions, both from the hydrogenation of nitriles and reductive amination.

Wu, Bang; Jiang, Xinyue; Liu, Yang; Li, Qiu-Yan; Zhao, Xinsheng; Wang, Xiao-Jun published the artcile< Vinylene-bridged donor-acceptor type porous organic polymers for enhanced photocatalysis of amine oxidative coupling reactions under visible light>, Safety of 4-Bromobenzylamine, the main research area is amine oxidative coupling photocatalysis porous organic polymer preparation property.

Porous organic polymers (POPs), owing to their abundant porosity, high stability and well-tunable properties, are promising candidates as heterogeneous photocatalysts for organic transformations. Here we report two vinylene-bridged donor-acceptor (D-A) structural POPs (TpTc-POP and TbTc-POP) that are facilely constructed by the electron-rich triarylamine and electron-deficient tricyanomesitylene as key building blocks by the organic base catalyzed Knoevenagel condensation. Both TpTc-POP and TbTc-POP possess hierarchical meso- and micro-pores with a high surface area. Furthermore, the unsubstituted vinylene linkages of D-A moieties in their polymer backbones extend their π-conjugation and render their broad absorption range in the visible-light region. Thus, these DA-POPs exhibited highly effective photocatalytic activities for aerobic oxidative coupling of amines to imines under visible light irradiation This study shows the great potential of conjugated POPs with a D-A structural feature in designing highly efficient and active heterogeneous photocatalytic systems.

Kandula, Venkata Ramana; Pothireddy, Mohanreddy; Babu, K. Suresh; Kapavarapu, Ravikumar; Dandela, Rambabu; Pal, Manojit published the artcile< Sonochemical synthesis of polyarylated oxazoles as potential cytotoxic agents>, Computed Properties of 3959-07-7, the main research area is polyarylated oxazole preparation ultrasound antitumor human.

The ultrasound assisted facile, rapid and one-pot synthesis of 2-aryl substituted 4,5-diphenyloxazoles I (Ar = C6H5, 4-FC6H4, 3-MeC6H4, etc.,) was achieved via the reaction of com. available benzoin (or 2-hydroxy-2-phenylacetophenone) with benzylamines in the presence of IBX under mild conditions. The methodol. involved initial IBX mediated conversion of benzoin to benzil and then reaction with benzylamine followed by intramol. cyclization (C-O bond formation) and finally aromatization in the presence of air in the same pot. The methodol. afforded a variety of desired products that were assessed for their cytotoxic properties against a number of cancerous and a non-cancerous cell lines. Compounds I (Ar = 4-MeOC6H4), I (Ar = 4-CF3OC6H4) and I (Ar = 3,4-CH3OC6H3) showed promising growth inhibition of these cell lines except the non-cancerous one and interactions with SIRT1 in silico as well as in vitro.

Wang, Hang; Zhang, Qing; Liu, Qing; Zhang, Na; Zhang, Jian-Yong; Fang, Yong-Zheng published the artcile< Bi2S3@NH2-UiO-66-S composites modulated by covalent interfacial reactions boost photodegradation and the oxidative coupling of primary amines>, Safety of 4-Bromobenzylamine, the main research area is bismuth sulfide UiO66 composite catalyst photodegradation oxidative coupling amine; mercapto functionalized UiO66 bismuth sulfide composite preparation photocurrent EIS.

Heterojunctions have attracted much attention due to the efficient separation and conduction of charge carriers in the photocatalytic reactions. However, the interfacial energy barrier between two components still limits the controllable assembly, separation, and conduction of photoexcited charge carriers, and further lower the photocatalytic activity. How to control the assembly of the heterojunction and accelerate the separation and conduction of photogenerated electron-holes by building a more intimate interfacial interaction is an important area of research. Herein, the authors report Bi2S3@NH2-UiO-66-S heterostructures prepared by the covalent interfacial reaction. Novel composites exhibit excellent efficiencies for the photodegradation of methylene blue and the oxidative coupling of benzylamine and its derivatives The turnover frequency is ∼8083μmol gcat-1 h-1. The super photocatalytic performance was attributed to the interfacial compactness by the covalent interfacial reaction. The expansion for the excellent performance was confirmed by UV-visible DRS, photocurrent measurement and EIS.

Lian, Chengxi; Zhang, Chaoying; Zhao, Yingchun; Wang, Hui; Li, Xiufen; Huang, Longjiang published the artcile< Oxidative coupling of primary amines to imines catalyzed by CoCl2·6H2O>, COA of Formula: C7H8BrN, the main research area is imine preparation green chem; primary amine oxidative coupling cobalt catalyst; benzimidazole preparation green chem; phenylenediamine benzylamine oxidative coupling cobalt catalyst.

A high-performance, readily available and eco-friendly cobalt catalyst has been suggested for the first time for the additive-free oxidative coupling of primary amines RCHR1NH2 (R = Ph, 4-chlorophenyl, thiophen-2-yl, etc.; R1 = H, Me) to imines RC(R1)=NCHRR1. Different substituted benzylamine and heteroaryl methanamine compounds could be transformed into their corresponding imines in good to excellent yields over this catalyst. Meanwhile, it has been demonstrated that this catalyst can also afford the oxidative coupling of various benzylamines R2CH2NH2 (R2 = Ph, 3-fluorophenyl, thien-2-yl, etc.) with o-phenylenediamine to produce benzimidazole derivatives I in medium to good yields.

Wang, Guanchao; Zhang, Ting; Yu, Weiwei; Si, Rui; Liu, Yuefeng; Zhao, Zhongkui published the artcile< Modulating Location of Single Copper Atoms in Polymeric Carbon Nitride for Enhanced Photoredox Catalysis>, Application of C7H8BrN, the main research area is copper atom polymeric carbon nitride photocatalyst photoredox benzylamine.

Introducing single-atom metals (SAMs) is a promising strategy to improve photocatalysis of polymeric carbon nitride (PCN), but current studies are limited to loading SAMs on the surface of PCN to serve as active sites. Herein, we report an intercalation-structured hollow carbon nitride sphere composed of carbon nitride nanosheets (HCNS) with atomically dispersed Cu1N3 moieties embedded within nanosheets (Cu1@HCNS) prepared by a facile mol. assembly approach. It exhibits far superior photoredox catalysis to the pristine HCNS and the modified HCNS with Cu1N3 moieties anchored on the surface of nanosheets (Cu1/HCNS) for solar hydrogen production (3261μmol g-1 h-1 rate with 7.1% of apparent quantum yield), in which the embedded single-atom Cu acts as a modifier to effectively modulate the electron structure and remarkably promote interfacial charge transfer of PCN rather than act as active sites to facilitate surface reaction. It can be extended to the nonoxygen coupling of benzylamine and derivants to corresponding imines, and the unexpectedly high reaction rate is achieved. The promoting effect strongly depends on the location of single-atom Cu in the PCN, and the coordination method is a very effective strategy to introduce single-atom metals in terms of the improvement in photocatalysis of PCN owing to the intensified metal-PCN interaction. This work opens up a window for further improving the photocatalytic efficiency of carbon nitride in terms of solar fuel production and clean organic synthesis.
