Recently I am researching about O-NITROSTYRENES; AROMATIC-AMINES; BOND; LIGAND; HYDROFORMYLATION; CARBONYLATION; COMPLEXES; CO; NITROBENZENE; MECHANISM, Saw an article supported by the National Key R&D Program of China [2018YFB1501600]; Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21773271, 21972151]. Published in SCIENCE PRESS in BEIJING ,Authors: Yang, L; Shi, LJ; Xia, CG; Li, FW. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone. HPLC of Formula: C8H7NO3

An efficient route for the palladium-catalyzed reductive aminocarbonylation of olefins with nitroarenes was developed using carbon monoxide (CO) as both reductant and carbonyl source, which enables facile access to amides with excellent regioselectivity and broad substrate scope. It is found that the counter anions of the Pd catalyst precursors significantly affect the reaction chemoselectivity and amide regioselectivity. Branched amides were mainly obtained with K2PdCl4 as the metal catalyst, and phosphine ligands had no influence on the regioselectivity but affected the catalytic reactivity. However, phosphine ligands had significant effects on aminocarbonylation regioselectivity when Pd(CH3CN)(4)(OTf)(2) was used; monodentate phosphines tended to form branched amides, and bidentate phosphines mainly formed linear amides. Trapping experiments, primary kinetic studies, and control reactions with all possible N-species reduced from nitroarene indicated that the catalytic synthesis of branched and linear amides produced nitrene (further converted to enamide) and aniline, respectively, different from the previous ligand-controlled regioselective synthesis of amides via the aminocarbonylation of olefins with amines. Furthermore, the proposed synthesis route could be applied in the synthesis of gram-scale propanil under mild conditions. (C) 2020, Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

While dual photocatalysis-transition metal catalysis strategies are extensively reported, the majority of systems feature two separate catalysts, limiting the potential for synergistic interactions between the catalytic centres. In this work we synthesised a series of tethered dual catalysts allowing us to investigate this underexplored area of dual catalysis. In particular, Ir(i) or Ir(iii) complexes were tethered to a BODIPY photocatalyst through different tethering modes. Extensive characterisation, including transient absorption spectroscopy, cyclic voltammetry and X-ray absorption spectroscopy, suggest that there are synergistic interactions between the catalysts. The tethered dual catalysts were more effective at promoting photocatalytic oxidation and Ir-catalysed dihydroalkoxylation, relative to the un-tethered species, highlighting that increases in both photocatalysis and Ir catalysis can be achieved. The potential of these catalysts was further demonstrated through novel sequential reactivity, and through switchable reactivity that is controlled by external stimuli (heat or light).

A new diamine bearing flexible ether, rigid pyridine, and bulky anthrone pendent group, 10,10-bis[4-(4-amino-2-pyridinoxy)phenyl]-9(10H)-anthrone (BAPPA), was prepared in three steps from anthrone. BAPPA was reacted with six conventional aromatic dianhydrides in N, N-dimethylacetamide (DMAc) to form the corresponding new poly(ether imide)s (PEIs) via the poly(ether amic acid) (PEAA) precursors with inherent viscosities ranging from 0.85 dL g(-1) to 1.26 dL g(-1) and thermal imidization. All the PEAAs could be cast from DMAc solution and thermally converted into transparent, flexible, and tough PEI films with tensile strength of 72.2-112.4 MPa, tensile modulus of 1.8-2.1 GPa, and elongation at break of 10-18%. These PEIs were predominantly amorphous and displayed excellent thermal stability with the glass transition temperature of 290-388 degrees C, the 5% weight loss temperature of 480-514 degrees C, and the residue of 68-43% at 800 degrees C in nitrogen. The PEIs derived from 1,4-bis(3,4-dicarboxyphenoxy)benzene dianhydride and 4,4 ‘-hexafluoroisopropylidenediphathalic anhydride exhibited excellent solubility in organic solvents such as N-methyl-2-pyrrolidinone, DMAc, N, N-dimethylformamide, pyridine, and even in tetrahydrofuran. Meanwhile, these PEIs also exhibited high optical transparency with the ultraviolet cutoff wavelength in the 374-427 nm range and the wavelength of 80% transparency in the range of 468-493 nm.

Membrane-bound pyrophosphatases (mPPases) regulate energy homeostasis in pathogenic protozoan parasites and lack human homologues, which makes them promising targets in e.g. malaria. Yet only few nonphosphorus inhibitors have been reported so far. Here, we explore an isoxazole fragment hit, leading to the discovery of small mPPase inhibitors with 6-10 mu M IC50 values in the Thermotoga maritima test system. Promisingly, the compounds retained activity against Plasmodium falciparum mPPase in membranes and inhibited parasite growth.

The first general palladium-catalyzed alpha-arylation of arylacetonitriles with aryl and heteroaryl sulfonates are reported. Pd(OAc)(2) associated with XPhos serves as the effective catalyst to facilitate this reaction. A broad range of electron-rich, -neutral, -deficient, and sterically hindered aryl/heteroaryl tosylates and mesylates are coupled with arylacetonitriles bearing different substituents to give the corresponding products in good to excellent yields. Catalyst loading down to 0.1 mol-% Pd was achieved, and 22 unprecedented compounds were synthesized from 43 demonstrated examples using this method. Its applicability with the modification of biological phenolic compounds was successfully demonstrated. The Pd/XPhos system catalyzed the alpha-arylation and followed by alkylation in one-pot sequential conditions, resulting in the direct synthesis of compounds containing quaternary center- and deuterium-containing compounds in good to excellent yields.

The reduction of graphene oxide (GO) was examined by using the extracts of different plants; cloves, white mulberry, black cumin seed, blackthorn, dark grape, and rosehip. The reduction efficiency of extracts was confirmed by XRD and spectroscopic analysis. The layered structure of reduced graphene and graphene nanocomposite decorated with palladium nanoparticles (PdNPs) was observed by electron microscopy techniques. This nanocomposite considered to be an active-selective catalyst for hydrogenation of nitroarenes in organic synthesis. This efficient catalyst can provide to develop clean, environmentally friendly, and energy-efficient production routes in industrial organic chemistry. It was concluded that the PdNPs/RGO catalyst showed high stability based on its reusing performance; seven times without loss of catalytic activity. (C) 2019 Hydrogen Energy Publications LLC.

Three new dimeric bis-guanidinate zinc(II) alkyl, halide, and hydride complexes [LZnEt](2) (1), [LZnI](2) (2) and [LZnH](2) (3) were prepared. Compound 3 was successfully employed for the hydrosilylation and hydroboration of a vast number of ketones. The catalytic performance of 3 in the hydroboration of acetophenone exhibits a turnover frequency, reaching up to 5800 h(-)(1), outperforming that of reported zinc hydride catalysts. Notably, both intra- and intermolecular chemoselective hydrosilylation and hydroboration reactions have been investigated.

Here we disclose a simple, visible-light-drivenZ-selective synthesis of methylthio-substituted 1,4-enedione in a single step promoted by Selectfluor. Dimethyl sulfoxide is used as both the ‘thio’ source and the solvent. Molecular iodine and potassium persulfate are used as catalyst and oxidant, respectively. White light (CFL-30W) is used as the light source. The proposed mechanism involves a Kornblum reaction followed by aldol reaction.
