The oxovanadium(IV) complexes [VO(acac)2(Hpz)]·HC(pz) 3 1·HC(pz)3 (acac = acetylacetonate, Hpz = pyrazole, pz = pyrazolyl) and [VOCl2{HOCH2C(pz) 3}] 2 were obtained from reaction of [VO(acac)2] with hydrotris(1-pyrazolyl)methane or of VCl3with 2,2,2-tris(1-pyrazolyl) ethanol. The compounds were characterized by elemental analysis, IR, Far-IR and EPR spectroscopies, FAB or ESI mass-spectrometry and, for 1, by single crystal X-ray diffraction analysis. 1 and 2 exhibit catalytic activity for the oxidation of cyclohexane to the cyclohexanol and cyclohexanone mixture in homogeneous system (TONs up to 1100) under mild conditions (NCMe, 24 h, room temperature) using benzoyl peroxide (BPO), tert-butyl hydroperoxide (TBHP), m-chloroperoxybenzoic acid (mCPBA), hydrogen peroxide or the urea-hydrogen peroxide adduct (UHP) as oxidants. 1 and 2 were also immobilized on a polydimethylsiloxane membrane (1-PDMS or 2-PDMS) and the systems acted as supported catalysts for the cyclohexane oxidation using the above oxidants (TONs up to 620). The best results were obtained with mCPBA or BPO as oxidant. The effects of various parameters, such as the amount of catalyst, nitric acid, reaction time, type of oxidant and oxidant-to-catalyst molar ratio, were investigated, for both homogeneous and supported systems.

Zeolite ZSM-5 is one of the major catalysts in the petroleum and finechemical industries. The synthesis of zeolite ZSM-5 is usually carried out at a temperature above 100 C using an immense amount of organic structuredirecting agents (OSDA). It is interesting to note that fine-tuning the initial gel mixture can be used to enhance the typical slow crystallization rate of ZSM-5. Herein, we report the effect of the surface-to-volume ratio of the reactor vessel on the crystallization of ZSM-5 at low temperature. The surface-to-volume ratio of the reactor vessel influences the heat-transfer during the synthesis, which further governs the crystallization of ZSM-5. It was found that the higher the surface-to-volume of the reactor, the more crystalline the resulting product. The products with the highest crystallinity exhibited a nearly spherical morphology composed of smaller ZSM-5 crystallites. This phenomenon allows the presence of inter-crystallite mesopores, which is an advantage for the catalytic reaction of bulky molecules.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: catalyst-ligand, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1941-30-6

Chemistry is an experimental science, SDS of cas: 1660-93-1, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1660-93-1, Name is 3,4,7,8-Tetramethyl-1,10-phenanthroline

A broad range of 1,10-phenanthroline substrates was efficiently C-H functionalised, providing rapid, gram-scale access to substituted heteroaromatic cores of broad utility. Furthermore, this C-H functionalisation pathway was extended to the synthesis of previously inaccessible, ultra-soluble, 2,9-bis-triazinyl-1,10-phenanthroline (BTPhen) ligands for advanced nuclear fuel cycles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 1660-93-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1660-93-1, in my other articles.

Application of 10495-73-5, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10495-73-5, Name is 6-Bromo-2,2′-bipyridine, molecular formula is C10H7BrN2. In a Article，once mentioned of 10495-73-5

The iron(II) triflate complex (1) of 1,2-bis(2,2?-bipyridyl-6-yl)ethane, with two bipyridine moieties connected by an ethane bridge, was prepared. Addition of aqueous 30 % H2O2 to an acetonitrile solution of 1 yielded 2, a green compound with lambdamax=710 nm. Moessbauer measurements on 2 showed a doublet with an isomer shift (delta) of 0.35 mm/s and a quadrupole splitting (DeltaEQ) of 0.86 mm/s, indicative of an antiferromagnetically coupled diferric complex. Resonance Raman spectra showed peaks at 883, 556 and 451 cm?1 that downshifted to 832, 540 and 441 cm?1 when 1 was treated with H2 18O2. All the spectroscopic data support the initial formation of a (mu-hydroxo)(mu-1,2-peroxo)diiron(III) complex that oxidizes carbon-hydrogen bonds. At 0 C 2 reacted with cyclohexene to yield allylic oxidation products but not epoxide. Weak benzylic C?H bonds of alkylarenes were also oxidized. A plot of the logarithms of the second order rate constants versus the bond dissociation energies of the cleaved C?H bond showed an excellent linear correlation. Along with the observation that oxidation of the probe substrate 2,2-dimethyl-1-phenylpropan-1-ol yielded the corresponding ketone but no benzaldehyde, and the kinetic isotope effect, kH/kD, of 2.8 found for the oxidation of xanthene, the results support the hypothesis for a metal-based H-atom abstraction mechanism. Complex 2 is a rare example of a (mu-hydroxo)(mu-1,2-peroxo)diiron(III) complex that can elicit the oxidation of carbon-hydrogen bonds.

Diastereomers of 2,2?-bis[4,6-dimethyl-1,3,2-dioxaphosphorinan-2-yloxy]-1,1?- binaphthyl, R-bis(4R,6R)-1, and S-bis(4R,6R)-2, have been synthesized. The solid state structure of S-bis(4S,6S)-1 and the platinum complex [PtCl2(1)] (3) of its enantiomer pair have been determined. The structure of 3 shows a slightly distorted square-planar geometry. The dihedral angle defined by the naphthyl rings in 3 is smaller (77.6(2)) than in the free ligand (103.0(2)). In the platinum- and rhodium-catalyzed asymmetric hydroformylation of styrene, the axial chirality in the bridge has been found to be determinate for the product configuration with a cooperative effect from the terminal groups. The maximum enantioselectivity (39% ee) and a remarkable high regioselectivity (84%) towards branched aldehyde was obtained with platinum system of a matched constellation of the ligand (S-bis(4R,6R)-2).

A sequential benzoin/Michael/acetalization tandem reaction catalyzed by NHC and amine together has been developed to assemble aromatic aldehydes and enals into chiral tetrahydrofuran derivatives bearing multiple functional groups and stereogenic centers with high stereoselectivity of up to 95:5 dr and 96% ee. The high yield and stereocontrol of this process may be due to both acid-promoted symmetrization of racemic acyloins and iminium ion activation of enals.

Zeolite ZSM-5 has been successfully produced from rice-husk by a low-cost process. Without expensive and toxic organic structure-directing agent, zeolite ZSM-5 can be obtained at temperature of 160 C, in 96 h at pH 11 by a seed-assisted hydrothermal method. Using this zeolite as a support, nano-sized TiO2/ZSM-5 photocatalysts were obtained by sol?gel method. The materials were characterized the structural and morphological properties. They were also examined activity for photocatalytic removal of toluene in humid condition. Synergistic adsorption?photocatalysis using TiO2/ZSM-5 can remove about 70% toluene at its concentration of 2400 ppm, water vapor content of 18.5 mg/L (relative humidity 60% at 25 C), and gas hourly space velocity (GHSV) of 5760 h?1. The toluene removal efficiency by the nano-sized TiO2/ZSM-5 photocatalyst was significantly higher than that by a commercial photocatalyst TiO2. The toluene removal in humid condition was remarkably enhanced on TiO2/ZSM-5 due to combination adsorption (on ZSM-5)?photocatalysis (on TiO2).

Objective: The present study attempted to evaluate the anti-biofilm activity of D-amino acids (D-AAs) on Pseudomonas aeruginosa and determine if the combination of D-AAs with tetracycline enhances the anti-biofilm activity in vitro and ex vivo. Methods: Different D-AAs were tested for antibiofilm activity against wild type P. aeruginosa PAO1 and two multidrug resistant P. aeruginosa clinical strains in the presence of sub inhibitory concentrations of tetracycline using crystal violet microtitre plate assay. Results were further validated using in vitro wound dressing and ex vivo porcine skin models followed by cytotoxicity and hemocompatibility studies. Results: D-tryptophan (5 mmol) showed 61 % reduction in biofilm formation of P. aeruginosa. Interestingly combinatorial effect of 5 mmol D-tryptophan and 0.5 minimum inhibitory concentration (MIC) (7.5mug/ml) tetracycline showed 90% reduction in biofilm formation. 5 mmol D-methionine shows 28 % reduction and combination with tetracycline shows 41% reduction in biofilm formation of P. aeruginosa. D-leucine and D-tyrosine alone or in combination with tetracycline did not show significant anti-biofilm activity. D tryptophan-tetracycline combination could reduce 80 % and 77 % reduction in biofilm formation in two multi drug resistant P. aeruginosa clinical strains. D-tryptophan-tetracycline-combination could also reduce 76% and 66% reduction in biofilm formation in wound dressing model and porcine skin explant respectively. The cytotoxicity and hemocompatibility studies did not show significant toxicity when this combination was used. Conclusion: The results established the potential therapeutic application of D-tryptophan alone or in combination with tetracycline for treating biofilm associated clinical problems caused by P. aeruginosa.
