Organocuprate cross-coupling: The central role of the copper(III) intermediate and the importance of the copper(I) precursor

(Chemical Equation Presented) CuIII in focus: The key intermediate in copper-mediated cross-coupling reactions has long been believed to be a “copper-(III) intermediate”. Investigation of reactions of a variety of methyl Gilman reagents Me2CuLi¡¤LiX with Etl using rapid-injection NMR spectroscopy conditions reveals a number of formally Cu III tetra-coordinate square-planar intermediates (see scheme) with a surprising range of stabilities.

Copper(II) and zinc(II) complexes with Hydrazone: Synthesis, crystal structure, Hirshfeld surface and antibacterial activity

The present study reports the synthesis and characterization of six Cu(II) and Zn(II) complexes with 2-cetylpyridinenicotinichydrazone (HL). The characterization of the complexes were applied by conductivity measurements and spectroscopic techniques (FT-IR, UV?Vis, ESI(+)-MS and NMR 1H). Four complexes have been studied by single crystal X-ray diffraction, [Cu(L)2] (1), [Zn(L)2] (2), [CuCl2(HL)] (3) and [CuBr2(HL)] (4). Important interactions upon the molecular packing were also performed by the analysis of their Hirshfeld surfaces and compared to the 2D-fingerprint plots. The characterizations indicates the formation of mononuclear Cu(II) and Zn(II) complexes with the hydrazone ligand coordinated to the metal ions in tridentate mode through the NNO chelating system. The antibacterial activity of HL and its metal complexes was tested against cariogenic bacteria strains.

ANTIMICROBIAL COMPOSITIONS FOR USE IN PRODUCTS FOR PETROLEUM EXTRACTION, PERSONAL CARE, WOUND CARE AND OTHER APPLICATIONS

Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial, materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing,.

Preparation of epitaxial YBa2Cu3O7-y films on CeO2-buffered yttria-stabilized zirconia substrates by fluorine-free metalorganic deposition

Epitaxial YBa2Cu3O7-y (YBCO) films of 120-550 nm thickness have been prepared by fluorine-free metalorganic deposition using a metal acetylacetonate-based coating solution on yttria-stabilized zirconia (YSZ) substrates with an evaporated CeO2 buffer layer. The YBCO films were highly (0 0 1)-oriented by X-ray diffraction theta-2theta scanning and phi{symbol} scanning. The YBCO films 120-400 nm in thickness demonstrated high critical current densities (Jc) with an average in excess of 3 MA/cm2 at 77 K using an inductive method. In particular, a 210-nm-thick film showed a Jc of 4.5 MA/cm2. These excellent properties are attributed to the high crystallinity, small in-plane fluctuation due to high epitaxy and to the microstructure free from grain boundaries in the YBCO films. Further increase of film thickness increased the fraction of irregularities, i.e., precipitates and micropores, in the film surfaces, resulting in lower Jc values.

Thiolate layers on metal sulfides characterised by XPS, ToF-SIMS and NEXAFS spectroscopy

Surface spectroscopic characterisation of some Cu and Ag thiolate multilayers on metal and metal sulfide substrates was undertaken to establish unequivocally the composition and possible orientation of the multilayer species. This information was sought to attempt to explain the undiminished floatability of sulfide minerals observed for collector coverage exceeding a monolayer. The thiol collectors investigated were dithiophosphate and 2-mercaptobenzothiazole (MBT), and bulk CuMBT and AgMBT complexes were prepared for comparison with the corresponding multilayers. Surface optimised synchrotron X-ray photoelectron spectra and partial electron yield near-edge X-ray absorption fine structure (NEXAFS) spectra confirmed that the Cu dithiolate, detected by secondary ion mass spectroscopy (SIMS), was no more than a minor constituent of the corresponding multilayer. The photoelectron spectra for multilayer CuMBT and AgMBT were similar to those for the corresponding bulk complexes. NEXAFS spectroscopy detected some CuII in bulk CuMBT prepared from cupric ions but not cuprous. The SIMS data were consistent with multilayer patches or islands on top of a chemisorbed monolayer and hence continued exposure of the monolayer in the presence of the multilayer. For each multilayer investigated, the SIMS data provided no evidence to support a multinuclear cluster structure as is present in the corresponding bulk thiolate, but nor could they exclude such a possibility. Angle-dependent NEXAFS spectroscopy at the N K-edge confirmed that MBT monolayers were aligned and revealed that the metal thiolate multilayer was not aligned relative to the substrate, but might nevertheless have been ordered in a cluster structure. It was surmised that undiminished floatability of sulfide minerals with multilayer collector coverage could probably be attributed to the patch-wise nature of the multilayer.

Development of environmentally friendly antifouling paints using biodegradable polymer and lower toxic substances

The development of new antifouling coatings with respect to the marine environment is actually crucial. The aim of the present work is to concept an erodible paint formulated with biodegradable polyester as binders and which combines two modes of prevention: chemical and physical repelling of biofouling. This system is principally dedicated to disturb durable settlement of microfouling. Each component was chosen according to its specific properties: chlorhexidine is a bisdiguanide antiseptic with antibacterial activity, zinc peroxide is an inorganic precursor of high instable entities which react with seawater to create hydrogen peroxide, Tween 85 is a non ionic surfactant disturbing interactions between colonizing organisms and surface. Obtained results highlighted the interest on mixing such molecules to obtain a promising coating with lower toxicity than traditional systems.

Synthesis, characterization and crystal structures of the bidentate Schiff base N,N?-bis(2-nitrocinnamaldehyde)ethylenediamine and its complex with CuNCS and triphenylphosphane

Reaction of copper(I) thiocyanate and triphenylphosphane with the bidentate Schiff base N,N?-bis(trans-2-nitrocinnamaldehyde)ethylenediamine {Nca2en, (1); systematic name (1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]}, C20H18N4O4, in a 1:1:1 molar ratio in acetonitrile resulted in the formation of the complex {(1E,1?E,2E,2?E)-N,N?-(ethane-1,2-diyl)bis[3-(2-nitrophenyl)prop-2-en-1-imine]-kappa2 N,N?}(thiocyanato-kappaN)(triphenylphosphane-kappaP)copper(I)], [Cu(NCS)(C20H18N4O4)(C18H15P)] or [Cu(NCS)(Nca2en)(PPh3)], (2). The Schiff base and copper(I) complex have been characterized by elemental analyses, IR, electronic and 1H NMR spectroscopy, and X-ray crystallography [from synchrotron data for (1)]. The molecule of (1) lies on a crystallographic inversion centre, with a trans conformation for the ethylenediamine unit, and displays significant twists from coplanarity of its nitro group, aromatic ring, conjugated chain and especially ethylenediamine segments. It acts as a bidentate ligand coordinating via the imine N atoms to the CuI atom in complex (2), in which the ethylenediamine unit necessarily adopts a somewhat flattened gauche conformation, resulting in a rather bowed shape overall for the ligand. The NCS- ligand is coordinated through its N atom. The geometry around the CuI atom is distorted tetrahedral, with a small N-Cu-N bite angle of 81.56(12) and an enlarged opposite angle of 117.29(9) for SCN-Cu-P. Comparisons are made with the analogous Schiff base having no nitro substituents and with metal complexes of both ligands.

Solution-based synthesis and characterization of Cu2ZnSnS 4 nanocrystals

(Figure Presented) Recent advances have been made in thin-film solar cells using CdTe and CuIn1-xGaxSe2 (CIGS) nanoparticles, which have achieved impressive efficiencies. Despite these efficiencies, CdTe and CIGS are not amenable to large-scale production because of the cost and scarcity of Te, In, and Ga. Cu2ZnSnS4 (CZTS), however, is an emerging solar cell material that contains only earth-abundant elements and has a near-optimal direct band gap of 1.45-1.65 eV and a large absorption coefficient. Here we report the direct synthesis of CZTS nanocrystals using the hotinjection method. In-depth characterization indicated that pure stoichiometric CZTS nanocrystals with an average particle size of 12.8 ¡À 1.8 nm were formed. Optical measurements showed a band gap of 1.5 eV, which is optimal for a single-junction solar device.
