Organocatalyzed Asymmetric alpha-Thiocyanation of Oxindoles: Synthesis of Chiral Tertiary 3-Thiocyanatoxindoles

An enantioselective thiocyanation of oxindoles has been developed for the first time using a bifunctional cinchona-derived organo-catalyst and N-thiocyanatophthalimide as the electrophilic thiocyanation source in the presence of 2-naphthol as the additive. Various enantioenriched 3,3?-disubstituted oxindoles with SCN-containing quaternary carbon stereocenters were synthesized under mild conditions in high yields (up to 99%) and good enantioselectivities (up to 6:94 er).

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.

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.

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.

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.

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.

Novel conductive radical cation salts based on methylenediselenotetraselenafulvalene (MDSe-TSF): A sign of superconductivity in kappa-(MDSe-TSF)2Br below 4 K

Seven conductive radical cation salts based on MDSe-TSF (methylenediselenotetraselenafulvalene) have been synthesized by electrocrystallization in the presence of Cl-, Br-, I3-, I2Br-, PF6-, ClO4-, and Cu(NCS)2- counter anions. The crystal appearances of these salts fairly depend on the anions employed. X-ray crystallographic analyses have revealed that the PF6 and ClO4 salts in the shape of brown thin plates adopt the theta-type structures characterized by the herringbone arrangement of donor stacks, whereas the Cl and Br salts in the shape of black thick plates favor the kappa-type structures with the orthogonal arrangement of donor dimers. Regardless of different crystal appearances or crystal packing patterns, all these salts show high conductivity (> 102 S cm-1) at room temperature and retain metallic properties down to 4.2 K. Of them, the Br salt shows a weak but distinct diamagnetic shielding signal below 4 K in the dc magnetization measurement under zero-field-cooled (ZFC) condition, suggesting a sign of superconductivity. The band calculations of both PF6 and Br salts demonstrate closed Fermi surfaces indicative of two-dimensional molecular conductors.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of CCuNS, you can also check out more blogs about1111-67-7
