The use of the nickel(ii) complex [(TEEDA)NiCl2] (1; TEEDA= N,N,N ‘,N ‘-tetraethyl-ethylendiamine) and nickel(0) complex [Ni(COD)(2)] (5) as pre-catalysts in the additive-free catalytic hydrogenation of benzonitrile (BN) is reported. In the presence of 1 (1 mol%), BN was hydrogenated under relatively mild reaction conditions (100 degrees C, 120 psi H-2, 72 h) to the corresponding secondary imine, N-benzylidenebenzylamine (BBA), in very good yield (83%). As a counterpart, 5 (1 mol%) selectively hydrogenated BN to benzylamine (BA) in excellent yield (96%) under similar reaction conditions (80 degrees C, 120 psi H-2, 24 h). In both cases, nickel nanoparticles (Ni-NPs) were identified as the catalytically active species. These Ni-NPs were formed in situ from 1 and 5 without external additives or additional stabilizers. The use of complex 5 was extended to the hydrogenation of different (hetero) aromatic and aliphatic nitriles.

In this paper, synthesized Fe3O4 nanoparticles applied as catalyst in photodegradation of Direct Red 23 (DR23) dye using photo-Fenton process in aqueous solution. The Fe3O4 nanoparticles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Design of experiments (DOE) based on Taguchi approach was used. Analysis the response of each experiment was based Signal to Noise (S/N) ratio was calculated. The effective parameters for the degradation of dye were determined and optimized using Taguchi (L-9 (3(4))) orthogonal array experimental design method with four factors having three levels for each factor. The Taguchi approach showed that pH 3 (level 1), catalyst amount = 25 mg/L (level 2), H2O2 concentration = 15 ppm (level 3), and temperature = 35 degrees C (level 3) was optimum conditions for this process. The factor most influencing the process was determined using analysis of variance (ANOVA) method. The most significant factor in this process was pH. The interaction between pH x catalyst amount was the most influencing interaction. The percent (p (%)) of each factor on the degradation of dye was found to be in the following the order: pH (50.306%), catalyst amount (6.887%), H2O2 concentration (39.272%), and temperature (3.456%). The percentage contribution of factors in this process was found to be in the following the order: pH (0.332), catalyst amount (0.101), H2O2 concentration (0.291), and temperature (0.082). So first order reaction with k = 0.0472 min(-1) was observed for the photocatalytic degradation reaction.

Adsorption of a diverse set of chemicals onto goethite was evaluated by column chromatography. The pH of the effluents was 4.7-5.2. Van der Waals forces dominate the exothermic adsorption of 8 nonpolar compounds (e.g., PAHs and chlorobenzenes). H-bonding is responsible for the adsorption of 32 mono-carboxylic acids (i.e., benzoic acids, naphthoic acids and acidic pharmaceuticals) and their adsorption tends to be endothermic. Steric effects significantly decreased the bonding of monocarboxylic acids with ortho-substitutions. Exothermic adsorption of 10 monophenols is controlled by weak H-bonding. Bonding of these 50 solutes onto goethite is totally reversible. In contrast, inner-sphere complexation of phthalic acid and chlortetracycline with goethite occurred according to their low desorption ratio (1.1%-54.4%). Polyparameter linear free energy relationship (PP-LFER) models were established to provide acceptable fitting results of the goethite-solute distribution coefficients (RMSE = 0.32 and 0.30 at 25 degrees C and 5 degrees C, respectively). It is worthy to note that steric effects must be considered to get a better prediction for compounds with ortho-substitutions. (C) 2018 Elsevier Ltd. All rights reserved.

In this paper, a comprehensive method for the identification of the unknown halogenated DBPs (X-DBPs, X = CI, Br, and I) in the tap water of Wuhan, China via liquid chromatography-high resolution mass spectrometry (LC-HRMS) was developed. 123 X-DBPs were identified through the stepwise procedure, 94 of them were newly identified, and 3 of them were confirmed by standards. Most X-DBPs were aliphatic compounds and highly unsaturated and phenolic compounds, some X-DBPs contained multiple halogen atoms and rich in carboxyl groups, such as C2H2O2BrCl, C2H2O2Br2, and C2H2O2ClI. It was worth noting that the concentration of some X-DBPs had the same trend with time. Most CI-DBPs remained stable and I-DBPs were detected occasionally by monitoring the change of concentration of these X-DPBs with the time during three consecutive months. The results demonstrate that the proposed method could provide valuable molecular formula and structure information on unknown multiple halogenated DBPs, or be used for the identification of other multiple halogenated organic compounds in different media.

A series of new Pd(II) complexes with simple structures were designed and synthesized for Suzuki-Miyaura coupling reactions of aryl chlorides. The new Pd(II) complexes contain bidentate amine ligands, and their structures were characterized by single-crystal X-ray diffraction. They are highly efficient for Suzuki-Miyaura coupling reactions of aryl chlorides with low catalyst loadings (0.01 mol %) in aqueous media at room temperature. Two possible reaction pathways involving a Pd-II(/0/)II and a Pd-II(/IV/II) catalytic cycle are proposed, and the mechanism was further investigated using density functional theory (DFT) calculations.

A series of novel N-phenylbenzamide-4-methylamine acridine derivatives were designed and synthesized based initially on the structure of amsacrine (m-AMSA). Molecular docking suggested that the representative compound 9a had affinity for binding DNA topoisomerase (Topo) II, which was comparable with that of m-AMSA, and furthermore that 9a could have preferential interactions with Topo I. After synthesis of 9a and analogues 9b-9f, these were all tested in vitro and the synthesized compounds displayed potent antiproliferative activity against three different cancer cell lines (K562, CCRF-CEM and U937). Among them, compounds 9b, 9c and 9d exhibiting the highest activity with IC50 value ranging from 0.82 to 0.91 mu M against CCRF-CEM cells. In addition, 9b and 9d also showed high antiproliferative activity against U937 cells, with IC50 values of 0.33 and 0.23 mu M, respectively. The pharmacological mechanistic studies of these compounds were evaluated by Topo I/II inhibition, western blot assay and cell apoptosis detection. In summary, 9b effectively inhibited the activity of Topo I/II and induced DNA damage in CCRF-CEM cells and, moreover, significantly induced cell apoptosis in a concentration-dependent manner. These observations provide new information and guidance for the structural optimization of more novel acridine derivatives.

A class of 2-aminopyridine 1-oxides are discovered to be effective ligands for the Cu-catalyzed amination of less reactive (hetero)aryl chlorides. A wide range of functionalized (hetero)aryl chlorides reacted with various aliphatic amines to afford the desired products in good to excellent yields under the catalyst of CuI/2-aminopyridine 1-oxides. Furthermore, the catalyst system worked well for the coupling of cyclic secondary amines and N-methyl benzylamine with (hetero)aryl chlorides.

Ln(NO3)(3)center dot nH(2)O reacted with 2,4-dichlorobenzoic acid (2,4-HDCB) and NaOH under solvothermal conditions of water and ethanol to yield four lanthanide-organic coordination polymers (CPs) [Eu(2,4-DCB)(3)(CH3CH2OH)(2)] (1) and [Ln(2,4-DCB)(3)(H2O)] [Ln = Gd (2), Tb (3), Dy (4)]. The second ligand 4,4′-bipyridine (4,4′-bpy) was introduced into the above reaction systems to provide four new lanthanide-organic CPs [Ln(2)(2,4-DCB)(6)(4,4′-bpy)(H2O)(2)] [Ln = Eu (5), Gd (6), Tb (7), Dy (8)]. Single-crystal and powder X-ray diffraction analyses reveal that CPs 1 and 2 possess similar one-dimensional (1D) structures, and CPs 2-4 and 5-8 are isostructural, respectively. In 1-4, the 2,4-DCB anions bridge the Ln(III) ions to form a 1D chain. In 5-8, six 2,4-DCB anions link two Ln(III) ions into a binuclear Ln(2)(2,4-DCB)(6) unit, and the Ln(2)(2,4-DCB)(6) units are further connected by the 4,4′-bpy co-ligands to generate a 1D chain. The photoluminescent and magnetic properties of 1-8 were investigated.

Computed Properties of C7H4Cl2O2. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Discovery of the first Mycobacterium tuberculosis MabA (FabG1) inhibitors through a fragment-based screening published in 2020, Reprint Addresses Flipo, M (corresponding author), Univ Lille, Inst Pasteur Lille, Drugs & Mol Living Syst U1177, INSERM, F-59000 Lille, France..

Mycobacterium tuberculosis (M.tb), the etiologic agent of tuberculosis, remains the leading cause of death from a single infectious agent worldwide. The emergence of drug-resistant M.tb strains stresses the need for drugs acting on new targets. Mycolic acids are very long chain fatty acids playing an essential role in the architecture and permeability of the mycobacterial cell wall. Their biosynthesis involves two fatty acid synthase (FAS) systems. Among the four enzymes (MabA, HadAB/BC, InhA and KasA/B) of the FAS-II cycle, MabA (FabG1) remains the only one for which specific inhibitors have not been reported yet. The development of a new LC-MS/MS based enzymatic assay allowed the screening of a 1280 fragment-library and led to the discovery of the first small molecules that inhibit MabA activity. A fragment from the anthranilic acid series was optimized into more potent inhibitors and their binding to MabA was confirmed by F-19 ligand-observed NMR experiments. (C) 2020 Elsevier Masson SAS.
