Ionic liquids (ILs) can be used to generate and stabilize metallic nanoparticles (MNPs) by several phys. and chem. routes. Here, the simultaneous decomposition of Ru and Cu organometallic precursors in IL is shown to yield core-shell Ru@CuNPs with smaller diameters and narrower size distributions than the corresponding monometallic NPs, in a broad range of Ru:Cu compositions They are probably formed by rapid nucleation of Ru cores followed by decomposition of the Cu precursor on their surface. This effect forces the formation of a bimetallic structure that does not form with the use of purely phys. processes such as PVD. These Cu, Ru, and Ru@CuNPs could be used for the formation of seed and barrier layers for the metalization of advanced interconnect structures.

An easy, efficient, and safe process is developed to metalize mesoporous Si (PSi) with Cu from the decomposition of a solution of mesitylcopper (CuMes) in an imidazolium-based ionic liquid (IL), [C1C4Im][NTf2]. The impregnation of a solution of CuMes in IL affords the deposition of metallic islands not only on the surface but also deep within the pores of a mesoporous Si layer with small pores <10 nm. Therefore, this process is well suited to efficiently and completely metalize PSi layers. An in-depth mechanistic study shows that metal deposition is due to the reduction of CuMes by surface silane groups rather than by Si oxidation as observed in aqueous or H2O-containing media. This could open a new route to the chem. metalization of PSi by less-noble metals difficult to attain by a conventional displacement reaction.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called A Pseudomonas putida capable of stereoselective hydrolysis of nitriles, published in 1997-02-28, which mentions a compound: 4553-62-2, mainly applied to stereoselective nitrile hydratase amide Pseudomonas; nitrilase stereoselective Pseudomonas, Safety of 2-Methylglutaronitrile.

P. putida NRRL-18668 contains a nitrile hydratase capable of stereoselective hydrolysis of 2-(4-chlorophenyl)-3-methylbutyronitrile at >90% enantiomeric excess (ee) to the (S)-amide. This soil isolate was recovered from enrichments using (R,S)-2-methylglutaronitrile as the sole nitrogen source. Enzyme expression is constitutive and does not show a high level of catabolite repression. The organism is capable of growth on a wide variety of aliphatic mono- and dinitrile compounds The hydrolysis activity on propionitrile is ∼10.3 μmol/h-mg wet cells. The enzyme in cell-free preparations is inhibited by a number of heavy metals, phenylhydrazine, and cyanide. Substrate specificity is broad, with highest rates shown on C4 and C5 aliphatic mononitriles. The strain appears somewhat unusual in its dependence on Co supplementation for maximum enzyme activity and the ability to hydrolyze some aromatic nitriles. This strain is also capable of a 2-step hydrolysis of 2-(4-isobutylphenyl)-propionitrile and 2-(6-methoxy-2-naphthyl)-propionitrile to the (S, with stereoselectivity residing primarily in the aliphatic amidase. This appears to be the 1st description of a stereoselective nitrile hydratase from a gram-neg. organism.

Let’s take a look at the latest research on this compound (cas:75732-01-3).

Homoat. polyanions of post-transition main-group metals, namely, Zintl anions, are precast in analogous Zintl phases and can react in solution to form new materials. Despite comprehensible reaction approaches, the formed products cannot be planned in advance, as hitherto undetected and therefore disregarded side reactions take place. The outcomes and interpretations of the reactions of Zintl anions are so far based mainly on crystal structures, which only allow characterization of the product that has the lowest solubility Here the authors present the results of their investigation of the stability of highly charged tin Zintl anions in liquid ammonia, which is not exclusively based on solution effects but also on the oxidative influence of the solvent. This allows for a deeper understanding of the ongoing processes in solution and opens doors to the directed synthesis of transition metal complexes of Sn44-, here shown by its reactivity towards MesCu.

Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II), is researched, Molecular C48H38CoN4O4, CAS is 28903-71-1, about Inductive and electrostatic effects on cobalt porphyrins for heterogeneous electrocatalytic carbon dioxide reduction. Author is Zhu, Minghui; Yang, Deng-Tao; Ye, Ruquan; Zeng, Joy; Corbin, Nathan; Manthiram, Karthish.

Electrochem. carbon dioxide reduction enables conversion of carbon dioxide into fuels and chems. with renewable energy input. Cobalt-based mol. complexes have exhibited high selectivity, activity, and stability for transforming carbon dioxide into carbon monoxide. Through evaluating immobilized cobalt porphyrins functionalized with various peripheral substituents, we demonstrated that their activity is affected not only by the electronegativity of the substituents, but importantly, also by the charge of the substituents. The performance of immobilized cobalt porphyrins can be improved by introducing electron-donating and pos. charged functional groups. Through kinetic studies, we were able to understand the mechanism by which electron-donating groups enhance the observed rates of carbon dioxide reduction and how cationic functionality may contribute towards electrostatic stabilization of the intermediate formed in the rate-determining step. Our methodol. provides a robust and exptl.-verified method of computationally predicting the electronic effect of peripheral substitution and hence the catalytic activity of substituted porphyrins.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Inhibitory effect of (s)-chlorohydrin on rat sperm motility and hyperactivation, published in 2012-09-30, which mentions a compound: 60827-45-4, Name is (2S)-(+)-3-Chloropropane-1,2-diol, Molecular C3H7ClO2, Synthetic Route of C3H7ClO2.

The effects of (S)-α-chlorohydrin (SACH) on rat epididymal sperm motility and hyperactivation and the mechanisms of the effects were studied. 20 Adult male Sprague-Dawley rats were divided randomly into 4 groups and dosed orally with 0, 2.5, 5.0, and 10mg/kg BW SACH for 52 days. After the cauda epididymal sperm were incubated under a capacitating condition for 5h, sperm motility and hyperactivation parameters were obtained by computer-assisted sperm anal. (CASA), and sperm-specific glyceraldehyde 3-phosphate dehydrogenase (GAPDS) activity, ATP (ATP), and cyclic adenosine monophosphate (cAMP) were assayed. The protecting effect of pentoxifylline (PTF) against SACH was also tested. The sperm from the SACH-treated rats showed significant decreases in curvilinear velocity (VCL), average path velocity (VAP), straight line velocity (VSL), and amplitude of lateral head movement (ALH) (P<0.01 of all), and an increase in linearity (LIN) (P<0.01). The SACH-treated rats had much less sperm population with VCL≥400μm/s or LIN≤20% than that of the control (P<0.05 and P<0.01, resp.), indicating that SACH diminishes hyperactivation of rat sperm. GAPDS activities were inhibited by SACH, and decreasing trends of ATP and cAMP levels were observed PTF rescued the cAMP level which was depressed by SACH, and alleviated partly the inhibition of sperm motility and hyperactivation. SACH impairs the motility and hyperactivation of rat sperm, which might be related to inhibition of GAPDS by SACH and subsequent defects of ATP and cAMP.

Application In Synthesis of (S)-4-Benzyl-2-(isoquinolin-1-yl)-4,5-dihydrooxazole. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: (S)-4-Benzyl-2-(isoquinolin-1-yl)-4,5-dihydrooxazole, is researched, Molecular C19H16N2O, CAS is 2058236-52-3, about Enantioselective Construction of α-Chiral Silanes by Nickel-Catalyzed C(sp3)-C(sp3) Cross-Coupling. Author is Yi, Hong; Mao, Wenbin; Oestreich, Martin.

An enantioselective C(sp3)-C(sp3) cross-coupling of racemic α-silylated alkyl iodides and alkylzinc reagents is reported. The reaction is catalyzed by NiCl2/(S,S)-Bn-Pybox and yields α-chiral silanes with high enantiocontrol. The catalyst system does not promote the cross-coupling of the corresponding carbon analog, corroborating the stabilizing effect of the silyl group on the alkyl radical intermediate (α-silicon effect). Both coupling partners can be, but do not need to be, functionalized, and hence, even α-chiral silanes with no functional group in direct proximity of the asym. substituted carbon atom become accessible. This distinguishes the new method from established approaches for the synthesis of α-chiral silanes.
