Polyacrylonitrile modified partially reduced graphene oxide composites for the extraction of Hg(II) ions from polluted water

Polyacrylonitrile nanoparticles grafted on ethylene diamine functionalized partially reduced graphene oxide (PAN-PRGO) was prepared via in situ emulsion polymerization and was further modified to contain amidoxime, amdinoethylene diamine, and carboxylic groups on the surface of the graphene nanosheets via partial hydrolysis of the nitrile groups on the polymer chains of the composite using (4% NaOH, 20 min) (HPAN-PRGO). The properties and morphologies of the prepared composites were compared through FTIR, UV-Vis, Raman spectra, XRD, SEM, TEM, and XPS analysis. The results revealed that polyacrylonitrile nanoparticles were grafted on the surface of the aminated graphene oxide nanosheets via the reaction between the free amino groups of the ethylene diamine modified graphene oxide nanosheets and nitrile groups of acylonitrile (AN). The obtained HPAN-PRGO composite was evaluated for its chelating property with Hg(II) ions. The effect of initial pH, initial concentration of the Hg(II), adsorbent dose, and contact time on the extraction of Hg(II) ions using HPAN-PRGO were investigated. The adsorption experiments indicated that HPAN-PRGO exhibits higher affinity toward Hg(II). The maximum uptake capacity for the extraction of Hg(II) ions on HPAN-PRGO was 324.0 mg/g at pH 5. The HPAN-PRGO shows a 100% removal of Hg(II) at concentrations up to 50 ppm, and the adsorption is exceptionally rapid showing more than 80.0% removal within 15 min and 100.0% of q(e) within 1.5 h at 800 ppm concentration. The Langmuir isotherm model and pseudo-second-order kinetic model have showed good fitness with the practical data. The XPS analysis of HPAN-PRGO before and after adsorption revealed the chelation adsorption mechanism between mercury and amine, amide, amidoxime, and carboxylic groups. After six adsorption-desorption cycles, the HPAN-PRGO could retain more than 90.0% of its original adsorption capacity. These results confirmed that HPAN-PRGO has exceptional performance for the removal of Hg(II) from wastewater. [GRAPHICS] .

New applications of N-acyliminium precursors: Tetracarbonyliron-mediated stereoselective alkylations of 5-(R)-isopropoxy-3-pyrrolin-2-ones

Lewis acid catalyzed allylic substitutions with several nucleophiles at C-5 of the cis-tetracarbonyliron complexes of N-acetyl- and N-tosyl-5-(R) -isopropoxy-3-pyrrolin-2-ones occur highly regio- and stereoselectively. The results are interpreted as being indicative of the intermediacy of a ( pi-allyl)tetracarbonyliron cation, with possible preceding formation of an N-acyl- or an N-tosyliminium ion.

Synthesis of a fluorinated derivative of sigma-1 receptor modulator E1R: 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide

The ozonation of N-Boc-protected 3-methylidene-4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one resulted in its transformation into 3-hydroxy4-phenyl-5-(trifluoromethyl)-3-pyrrolin-2-one. Catalytic hydrogenation of its O-Boc-protected derivative introduced a way to reduce the double bond in combination with elimination of the hydroxy group leading to the formation of 4-phenyl-5-(trifluoromethyl)pyrrolidin-2-one as an intermediate in the synthesis of fluorinated E1R structural derivative 2-[5-oxo-3-phenyl-2-(trifluoromethyl)pyrrolidin-1-yl]acetamide.

NMR spin trapping: Detection of free radical reactions using a phosphorus-containing nitrone spin trap

This study employs P-31-nuclear magnetic resonance (NMR) to probe for changes in molecular structure arising from reactions between free radicals and a phosphorus-containing nitrone spin trap, 5-diethoxyphosphoryl-5-methyl-1-pyrroline-N-oxide (DEPMPO), A number of biologically relevant free radical reactions were detected: a) reactions of DEPMPO with OH resulted in a new P-31-NMR resonance at 27.05 ppm (shifted from the parent compound at 23.67 ppm); evidence suggests that this species is a diamagnetic hydroxy-pyrrolidone reduction product; b) P-31-NMR spectra of DEPMPO/(CH3)-C-. reactions resulted in peaks at 24.54, 30.83, and 32.31 ppm, while DEPMPO/(CH2OH)-C-. produced peaks at 24.05, 30.80 and 32.52 ppm; in the presence of excess ascorbate, only resonances between 30 and 32 ppm were evident, which we have tentatively assigned to the hydroxylamine isomers of their respective adducts; and c) reaction of DEPMPO with O-2(.-), produced by xanthine/xanthine oxidase or stimulated neutrophils, resulted in a single line, indistinguishable from DEPMPO/(OH)-O-. reaction products, We conclude that NMR spin trapping is a useful approach for detecting free radical reaction pathways. It may have future applications for human free radical biology and imaging. Magn Reson Med 42:228-234, 1999. (C) 1999 Wiley-Liss, Inc.

Synthesis of 3-Alkoxy-4-Pyrrolin-2-ones via Rhodium(II)-Catalyzed Denitrogenative Transannulation of 1H-1,2,3-Triazoles with Diazo Esters

A method for the synthesis of densely substituted 4-pyrrolin-2-ones by Rh(II)-catalyzed denitrogenative transannulation of 1-alkyl-4-aryl-1H-1,2,3-triazoles with diazo esters has been developed. The reaction proceeds via an attack of the rhodium-bound carbene at the N2 atom of the triazole and the formation of unstable 3,4-dihydro-1,2,4-triazine, which further undergoes ring contraction to a 4-pyrrolin-2-one under rhodium catalysis. The method is inapplicable to 1,2,3-triazoles with primary alkyl substituent at C4, which afford stable 1,2,3-triazol-3-ium ylides as the main products.

Discovery of 3-hydroxy-3-pyrrolin-2-one-based mPGES-1 inhibitors using a multi-step virtual screening protocol

Targeting microsomal prostaglandin E-2 synthase-1 (mPGES-1) represents an efficient strategy for the development of novel drugs against inflammation and cancer with potentially reduced side effects. With this aim, a virtual screening was performed on a large library of commercially available molecules using the X-ray structure of mPGES-1 co-complexed with a potent inhibitor. Combining fast ligand-based shape alignment, molecular docking experiments, and qualitative analysis of the binding poses, a small set of molecules was selected for the subsequent steps of validation of the biological activity. Compounds 2 and 3, bearing the 3-hydroxy-3-pyrrolin-2-one nucleus, showed mPGES-1-inhibitory activity in the low micromolar range. These data highlighted the applicability of the reported virtual screening protocol for the selection of new mPGES-1 inhibitors as promising anti-inflammatory/anti-cancer drugs.

Homorubins and homoverdins

The syntheses are described for centrally expanded bilirubin analogs: b-homorubins with propionic and butyric acid groups in the positions corresponding to the propionic acids of bilirubin. Their syntheses were accomplished by coupling two equivalents of a reactive monopyrrole (5-(bromomethylene)pyrrolin-2-one) to a dipyrrylethane. The corresponding b-homoverdins and dehydro-b-homoverdins were prepared by dehydrogenating the rubins or their dimethyl esters using DDQ. As supported by NMR measurements and molecular mechanics calculations, the homorubins are found to engage in conformation-determining intramolecular hydrogen bonding between the dipyrrinone and carboxylic acid moieties. Likewise, the homoverdins are believed to favor intramolecularly hydrogen-bonded conformations.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 611-64-3 is helpful to your research. Recommanded Product: 9-Methylacridine.

Conjugate addition reactions of alpha-aminoalkylcuprates with alpha,beta-alkenyl-, alpha,beta-alkynyl-, alpha,beta-beta,gamma-allenyl-, and alpha,beta-gamma,delta-dienyl carboxylie acid derivatives, nitriles, and sulfoxides

alpha -Aminoalkylcuprates prepared from alpha -lithio carbamates and CuCN.2LiCl participate in 1,4-addition reactions with alpha,beta -unsaturated esters, thiol esters, imides, and nitriles in poor to excellent yields depending upon the electron-withdrawing substituent and the substitution pattern of the unsaturated substrate. These reagents also undergo conjugate addition reactions with alpha,beta -alkynyl esters, sulfoxides, and nitriles and with alpha,beta-beta,gamma -unsaturated allenyl esters. Excellent stereocontrol is achieved in the conjugate additions of alpha -aminoalkylcuprates to the allenyl esters, while poor stereoselectivity results in the conjugate additions to the alkynyl derivatives. Deprotection and cyclization of the alkynyl adducts affords pyrrolin-2-ones, while similar treatment of the allenyl adducts affords 4-alkylidine- pyrrolidin-2-ones and pyrrolizidinones.
