A three-fold interpenetrated coordination polymer [Cd-2(L)(bibp)(3)](n) (1) (114L = 5,5′-(1,4-phenylenebis(methoxy))diisophthalic acid, bibp = 4,4′-bis(imidazolyl)biphenyl) has been rationally constructed, successfully solvothermally synthesized and fully characterized. Complex 1 shows a 3D three-fold interpenetrated novel topological framework with the point symbol (4. 6(9))2(4(2). 6(2). 7. 8), and represents a variety of potential applications. Luminescence studies demonstrate that 1 has high selectivity and sensitivity for pollutant Cr(VI) (CrO42- and Cr2O72-) anion and Fe(III) cation; Photocatalytic studies show that 1 exhibits great degradation activity of three organic dyes (methylene blue (MB), Rhodamine B (RhB) and MalachiteGreen oxalate (MGO)). Furthermore, the possible mechanisms of the luminescent quench and photocatalytic properties have been deduced.

We report that the nucleophilic acyl substitution reaction of aliphatic and (hetero)aromatic amides by organolithium reagents proceeds quickly (20 s reaction time), efficiently, and chemoselectively with a broad substrate scope in the environmentally responsible cyclopentyl methyl ether, at ambient temperature and under air, to provide ketones in up to 93 % yield with an effective suppression of the notorious over-addition reaction. Detailed DFT calculations and NMR investigations support the experimental results. The described methodology was proven to be amenable to scale-up and recyclability protocols. Contrasting classical procedures carried out under inert atmospheres, this work lays the foundation for a profound paradigm shift of the reactivity of carboxylic acid amides with organolithiums, with ketones being straightforwardly obtained by simply combining the reagents under aerobic conditions and with no need of using previously modified or pre-activated amides, as recommended.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 19982-07-1, Name is N-(3,5-Dimethyladamantan-1-yl)acetamide, formurla is C14H23NO.

The hydrodynamic characteristics of liquid-liquid plug flow were studied in microchannels with 0.2 and 0.5 mm ID both experimentally and numerically. For the experiments high speed imaging and bright field micro-Particle Image Velocimetry were used, while the numerical simulations were based on the volume-of-fluid (VOF) method. The two immiscible liquids were a 1 M HNO3 aqueous solution which formed the dispersed plugs and a mixture of 0.2 M n-octyl(phenyl)-N, N-diisobutylcarbamoylmethypho sphine oxide (CMPO) and 1.2 M Tributylphosphate (TBP) in the ionic liquid 1-butyl-3-methylimidazolium bis[(trifluoromethyl) sulfonyl] amide ([C(4)min][NTf2]). The thickness of the film surrounding the plugs, and the plug velocity and length were measured and compared against literature correlations. For the cases studied (0.0224 < Ca < 0.299) it was observed that the liquid film was largely affected by the changes in the shape of the front cap of the plug. The plug length was affected by both the Capillary number and the ratio of the aqueous to ionic liquid phase flow rates while the plug volume depended on the channel diameter and the mixture velocity. The numerical simulations showed that, in agreement with the measurements, a parabolic velocity profile develops in the middle of the plugs while the circulation patterns in the plug are affected by the channel size. The pressure profile along the channel with a series of plugs and slugs was predicted numerically while the pressure drop agreed well with a correlation which included the dimensionless slug length and the ratio Ca/Re.

Doxorubicin (DOX) is a leading cytostatic drug with many adverse effects in use. We are still looking for methods that will allow us to preserve the therapeutic effect against the tumor cells and reduce the toxicity to the normal cells. In our work, we obtained amide derivatives of DOX by reaction of the amino group with alpha-linolenic (LNA) and docosahexaenoic (DHA) acids (2, 3), as well as double-substituted derivatives via amide and ester linkages (4, 5). The structures of the compounds were confirmed by Proton Nuclear Magnetic Resonance (1H NMR), Carbon-13 Nuclear Magnetic Resonance (13C NMR), and High Resolution Mass Spectrometry (HRMS) analyses. For all compounds 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) assay was used to determine the cytotoxic effect on human cancer cell lines (SW480, SW620, and PC3) and Chinese hamster lung fibroblasts (V79) that were used as a control. The cytotoxic activity was established by calculation of the inhibitory concentration IC50. In addition, a cytotoxic capacity against tumor cells for tested compounds was expressed as a selectivity factor (selectivity index, SI). Lactate dehydrogenase (LDH) assay was performed for all compounds to assess the level of cell damage. To explain the basic mechanism of cell death induction the Annexin V-FITC/IP flow cytometry analysis was investigated. We found that all studied conjugates exhibit lower cytotoxicity but higher selectivity than DOX. Among the all derivatives, the conjugates formed by the amide and ester linkages (4, 5) were found to be more promising compared with conjugates (2, 3) formed only by the amide linkage. They show high cytotoxicity toward the tumor cell lines and moderate cytotoxicity towards the normal cell line.

The asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680 are reported. Conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to the requisite (E)-alpha,beta-unsaturated ester followed by in situ enolate oxidation with (-)-(camphorsulfonyl)oxaziridne (CSO) gave the corresponding anti-alpha-hydroxy-beta-amino esters. Sequential Swern oxidation followed by diastereoselective reduction gave the corresponding syn-alpha-hydroxy-beta-amino esters. Subsequent N-debenzylation (i.e., hydrogenolysis for microginin 612, and NaBrO3-mediated oxidative N-debenzylation for microginins 646 and 680) followed by acid catalysed ester hydrolysis gave the corresponding syn-alpha-hydroxy-beta-amino acids, the N-terminal components of microginins 612, 646 and 680, in good yield. An analogous strategy for elaboration of the enantiopure anti-alpha-hydroxy-beta-amino esters facilitated the asymmetric synthesis of the corresponding C(2)-epimeric alpha-hydroxy-beta-amino acids.

Accumulation of U(VI) on the Pantoea sp TW18 isolated from radionuclide-contaminated soils

Pantoea sp. TW18 isolated from radionuclide-contaminated soils was used for the bioremediation of radionuclides pollution. Accumulation mechanism of U(VI) on Pantoea sp. TW18 was investigated by batch experiments and characterization techniques. The batch experiments revealed that Pantoea sp. TW18 rapidly reached accumulation equilibrium at approximately 4 h with a high accumulation capacity (79.87 mg g(-1) at pH 4.1 and T = 310 K) for U(VI). The accumulation data of U(VI) onto Pantoea sp. TW18 can be satisfactorily fitted by pseudo-second-order model. The accumulation of U(VI) on Pantoea sp. TW18 was affected by pH levels, not independent of ionic strength. Analysis of the FT-IR and XPS spectra demonstrated that accumulated U(VI) ions were primarily bound to nitrogen- and oxygen-containing functional groups (i.e., carboxyl, amide and phosphoryl groups) on the Pantoea sp. TW18 surface. This study showed that Pantoea sp. TW18 can be considered as a promising sorbent for remediation of radionuclides in environmental cleanup.

(Nano)Fibrillar morphology development in biobased poly(butylene succinate-co-adipate)/poly(amide-11) blown films

Thin films with (nano)fibrillar morphologies were successfully obtained in fully-biobased poly(butylene succinate-co-adipate)/poly(amide-11) blends (PBSA/PA11, 85/15 wt/wt) using an extrusion-blowing process. Impacts of PA11 grade and take-up ratio on the morphology of PBSA/PA11 were particularly highlighted. Scanning electron microscopy analyses indicated that PA11 with high melt volume-flow rates are beneficial to the development of (nano)fibrillar morphologies in PBSA/PA11 blown film. On the contrary, unstable film blowing processing without fibrillar morphologies was attested for PA11 with low melt volume-flow rates. Increasing the take-up ratio during extrusion-blowing of PBSA/PA11 clearly generates finer PA11 (nano)fibrils into PBSA. Fibril diameters down to 300 nm could be reached with an optimal PA11 grade promoting enhanced mechanical properties (higher ductility and toughness). The formation of stable PA11 (nano)fibrils into PBSA is discussed via rheological assessments of viscosity/elasticity ratio. A specific attention was finally paid to the PBSA strain-hardening behavior in PBSA/PA11 using elongational rheological tests. PA11 (nano)fibrillation helps maintaining the strong PBSA strain-hardening and thus play a major role on the processability of PBSA/PA11 blends by extrusion blowing. As a conclusion, the PA11 grade represents a crucial parameter to control the production of PBSA/PA11 blown films with refined (nano)fibrillar structures and enhanced physico-chemical properties.

Site-selective C-H bond carbonylation with CO2 and cobalt-catalysis

Utilization of anthropogenic greenhouse gas CO2 for catalytic C-C bond formation via conversion to essentially valuable C1 synthons like CO is very challenging. The requirement of an efficient catalyst that has the ability to convert CO2 into CO and activate inert C-H bonds is the bottleneck. We herein demonstrate a tandem approach accomplished in a two-chamber system for efficient fluoride-mediated generation of CO from CO2 using disilane as a deoxygenating reagent and utilization of the in situ-produced CO gas for C-H bond carbonylation using earth-abundant cobalt catalysts. The ease of handling CO2 gas at atmospheric pressure allows us to prepare C-13 labelled compounds which are otherwise difficult to achieve. The procedure developed makes it possible to utilize CO2 as a CO source, which can be widely applied as a C1 synthon that can be incorporated between C-H and N-H bonds of aromatic, hetero-aromatic and aliphatic carboxamides for the synthesis of various cyclic imides including spirocycles in a site-selective fashion. The late-stage derivatization of a well-known angiotensin receptor blocker (ARB), Telmisartan, and a well-known drug for very low-density lipoproteins (VLDLs), Gemfibrozil, is demonstrated. Further, to showcase the generality of the reaction, various pharmacologically important and privileged scaffolds like xanthone, coumarin and isatin have been synthesized with CO2 under atmospheric pressure.

Diffusion-Enhanced Amide Bond Formation on a Solid Support

Mixing of polystyrene resins in solid-phase synthesis is performed by shaking or gentle agitation of the reaction vessel to avoid breaking the brittle beads. These mixing strategies result in poor diffusion to and into the beads. Using a large excess of reagents is the common way to compensate for these deficiencies. We use fast overhead stirring for performing coupling reactions on a solid support. We show that fast overhead stirring enhances the efficiency of amide bond formation on the solid support compared to the state-of-the-art mixing method, while preserving the integrity of the beads. We find that fast overhead stirring minimizes the effect of decomposition of the activated species by increasing the diffusion-dependent coupling reaction. This allows decreasing the excess of reagents used for the multistep synthesis of peptides, thus providing a greener and more sustainable alternative for peptide synthesis on solid supports.

Significance of N-moieties in regulating the electrochemical properties of nano-porous graphene: Toward highly capacitive energy storage devices

The effects of N doping concentration and dopant moieties on the electrochemical properties of nanoporous graphene and their dependence on annealing temperature are investigated. Four types of N moieties – amide, amine, graphitic-N, and oxidized-N – are obtained, which transformed into pyridinic-N and pyrrolic-N upon annealing. The diffusion coefficient (0′) of the ions in the electrode is the maximum at 400 degrees C because of a high level of N doping, whereas the second highest D’ value is obtained at 700 degrees C owing to a high level of reduction and N doping. The highest specific capacitance is obtained for the sample annealed at 400 degrees C. (C) 2018 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
