Rhodium-Catalyzed Chemoselective Hydrosilylation of Nitriles to an Imine Oxidation Level Enabled by a Pincer-type Group 13 Metallylene Ligand

Syntheses and catalytic application of rhodium complexes having a pincer-type group 13 metallylene ligand are reported. The (PGaP)-P-I-Rh complex exhibited high chemoselectivity for hydrosilylation of nitriles to an imine oxidation level, realizing efficient synthesis of oximes from nitriles with good functional group compatibility. A rhodium monohydride complex stabilized with PPh3 was synthesized and structurally characterized as a derivative of a plausible rhodium hydride intermediate.

Electroless Deposition of Ni-P Coatings on HNBR for Low Friction Rubber Seals

This paper reports a simple and cost-effective procedure to coat hydrogenated nitrile butadiene rubber (HNBR) with a well-adherent Ni-P film by using the electroless plating method. A HNBR surface functionalization process was first optimized, creating an interpenetrating network with polyvinylpyrrolidone (PVP). Silver nanoparticles were deposited on PVP and acted as catalysts for the Ni-P film deposition, eliminating the expensive tin-palladium sensitization/activation step. A homogeneous, low phosphorous Ni-P film was obtained after 60-120 min of plating in an alkaline bath, with an average thickness of 3 to 10 mu m, respectively. The PVP internetwork played an important role on the strong adhesion of the film, 1.0 +/- 0.5 MPa. The tribological behavior of Ni-P-plated HNBR samples was studied for 1, 5 and 10 N applied loads under dry sliding on a pin-on-disc configuration and the coefficient of friction (CoF) was reduced by similar to 30-49%, compared to uncoated HNBR (loads 1-5N). Based on these results, Ni-P-coated rubber can be regarded as a novel solution for enhancement of the tribological behavior of dynamic seals; it can be regarded as a means to avoid machinery failure. This method offers an alternative to the diamond-like carbon (DLC) coatings.

Reactions with pyrrolidine-2,4-diones, part 4*: Synthesis of some 3-substituted 1,5-diphenylpyrrolidine-2,4-diones as potential antimicrobial, anti-HIV-1 and antineoplastic agents

The condensation of 1,5-dipheiiylpyrrolidine-2,4-dione (1) with ethyl orthoformate yielded 3-ethoxymethylene-1,5-diphenylpyrrolidinc-2,4-dione (2). Reaction of the latter with hydrazine hydrate, secondary amines 7a-c or urea afforded the corresponding 3-substituted aminomethylene-1,5-diphenylpyrrolidene-2,4-diones 3, 8a-c or 9. On the other hand, condensation of 3 With veratraldehyde (5a) yielded 3-[(3,4-dimethoxybenzylidene)hydrazinomethylene]-1,5-diphenylpyrrolidine-24-dione (6). Whereas, cyclization of 9 with the reactive malonate ester 11 produced 3-[(5-butyl-4-hydroxy-2,6dioxo- 1,2,3,6- tetralhydropyrimidin-1-yl) methylene]-1,5-diphenylpyrrolidine-2,4-dione (12). The condensation of some selected aromatic aldehydes 5a-c and addition of morpholine (7c) or piperidine (7d) to some of the resulting 3-arylidene,1,5-diphenylpyrrolidine-2,4-diones 13b, e gave the respective 3-substituted methyl-4-hydroxy-1,5-diphenyl-Delta (3)-pyrrolin-2-ones 14a-c. Selected members of the new series were screened for their in vitro antimicrobial, anti-HIV-1 and antineoplastic activities. Two compounds 14a, b showed pronounced inhibitory activities against Gram-positive bacteria; whereas, in the in vitro anti-HIV-1 screening, only one compound Be displayed a moderate activity. However, in the antineoplastic screening protocol, the tested compounds were devoid of activity.

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] .

Visible-Light-Promoted Metal-Free Synthesis of (Hetero)Aromatic Nitriles from C(sp(3))-H Bonds**

The metal-free activation of C(sp(3))-H bonds to value-added products is of paramount importance in organic synthesis. We report the use of the commercially available organic dye 2,4,6-triphenylpyrylium tetrafluoroborate (TPP) for the conversion of methylarenes to the corresponding aryl nitriles via a photocatalytic process. Applying this methodology, a variety of cyanobenzenes have been synthesized in good to excellent yield under metal- and cyanide-free conditions. We demonstrate the scope of the method with over 50 examples including late-stage functionalization of drug molecules (celecoxib) and complex structures such as l-menthol, amino acids, and cholesterol derivatives. Furthermore, the presented synthetic protocol is applicable for gram-scale reactions. In addition to methylarenes, selected examples for the cyanation of aldehydes, alcohols and oximes are demonstrated as well. Detailed mechanistic investigations have been carried out using time-resolved luminescence quenching studies, control experiments, and NMR spectroscopy as well as kinetic studies, all supporting the proposed catalytic cycle.

Identification of the C4 ‘-Oxidized Abasic Site as the Most Abundant 2-Deoxyribose Lesion in Radiation-Damaged DNA Using a Novel HPLC-Based Approach

A novel analytical high-performance liquid chromatography (HPLC)-based method of quantification of the yields of C4′-oxidized abasic sites, 1, in oxidatively damaged DNA has been elaborated. This new approach is based on efficient conversion of 1 into N-substituted 5-methylene-Delta(3)-pyrrolin-2-ones, 2, upon treatment of damaged DNA with primary amines in neutral or slightly acidic solutions with subsequent quantification of 2 by HPLC. The absolute and relative radiation-chemical yields of 1 in irradiated DNA solutions were re-evaluated using this method. The yields were compared with those of other 2-deoxyribose degradation products including 5-methylene-2(5H)-furanone, malondialdehyde, and furfural resulting from the C1′, C4′ and C5′-oxidations, respectively. The yield of free base release (FBR) determined in the same systems was employed as an internal measure of the total oxidative damage to the 2-deoxyribose moiety. Application of this technique identifies 1 as the most abundant sugar lesion in double-stranded (ds) DNA irradiated under air in solution (36% FBR). In single-stranded (ss) DNA this product is second by abundance (33% FBR) after 2-deoxyribonolactones (C1′-oxidation; 43% FBR). The production of nucleoside-5′-aldehydes (C5′-oxidation; 14% and 5% FBR in dsDNA and ssDNA, respectively) is in the third place. Taken together with the parallel reaction channel that converts C4′-radicals into malondialdehyde and 3′-phosphoglycolates, our results identify the C4’-oxidation as a prevalent pathway of oxidative damage to the sugar-phosphate backbone (50% or more of all 2-deoxyribose damages) in indirectly damaged DNA.
