A simple synthesis of metallocene aldehydes from lithiometallocenes and N,N-dimethylformamide: ferrocene and ruthenocene aldehydes and 1,1′-dialdehydes

Lithioferrocene, 1,1′-dilithioferrocene, lithioruthenocene and 1,1′-dilithioruthenocene all react with N,N-dimethylformamide in diethyl ether to produce the respective aldehydes.The lithiation of the two metallocenes can be steered to maximize the formation of only one of the two aldehydes by choosing either n-butyllithium in the presence of tetramethylethylenediamine (TMEDA) or t-butyllithium (tBuLi) as the metallating reagent: ferrocene mono-aldehydes or 1,1′-dialdehydes are formed with good yields (91percent and 85percent respectively, based on ferrocene), lower yields (50percent) of ruthenocene-1,1′-dialdehyde were obtained under the standard conditions, because the 1,3,1′-trialdehyde also formed in significant (19percent) amounts.Monolithiation by nBuLi and the formation of the ruthenocene monoaldehyde (yield, 66percent) are favoured when TMEDA is used in only catalytic amounts; lithiation of ruthenocene by tBuLi selectively leads to monolithioruthenocene and the mono-aldehyde (yield, 91percent).The products are easily purified by column chromatography.The simplicity and the high yield of these reactions make them much more desirable than the previously known multistep procedures.

The role of an amino acid triad at the entrance of the heme pocket in human serum albumin for O2 and CO binding to iron protoporphyrin IX

Complexation of iron(II) protoporphyrin IX (Fe2+PP) into a genetically engineered heme pocket on recombinant human serum albumin (rHSA) creates an artificial hemoprotein which can bind O2 reversibly at room temperature. Here we highlight a crucial role of a basic amino acid triad the entrance of the heme pocket in rHSA (Arg-114, His-146, Lys-190) for O 2 and CO binding to the prosthetic Fe2+PP group. Replacing His-146 and/or Lys-190 with Arg resolved the structured heterogeneity of the possible two complexing modes of the porphyrin and afforded a single O 2 and CO binding affinity. Resonance Raman spectra show only one geometry of the axial His coordination to the central ferrous ion of the Fe 2+PP.

Patterning of L10 FePt nanoparticles with ultra-high coercivity for bit-patterned media

L10-ordered FePt nanoparticles (NPs) with ultra-high coercivity were directly prepared from a new metallopolyyne using a one-step pyrolysis method. The chemical ordering, morphology and magnetic properties of the as-synthesized FePt NPs have been studied. Magnetic measurements show the coercivity of these FePt NPs is as high as 3.6 T. Comparison of NPs synthesized under the Ar and Ar/H2 atmospheres shows that the presence of H2 in the annealing environment influences the nucleation and promotes the growth of L10-FePt NPs. Application of this metallopolymer for bit-patterned media was also demonstrated using nanoimprint lithography.

Semiconductor Property and Corrosion Behavior of Passive Film Formed on Steel with Zinc Coating in 5% NaCl Solution

The initial stage of corrosion behavior and the semiconductor property of a passive film formed on steel with zinc coating were investigated in 5?wt.% NaCl solution using scanning electrochemical microscopy (SECM), electrochemical impedance spectroscopy (EIS), potential-capacitance measurement and the Mott?Schottky analysis method. The SECM test results reveal that the Faradic currents on the tip of the ultramicro electrode decreased with the extension of immersion time, suggesting that the coating was slowly degrading, and the water and ions gradually permeated into the coating. The tip current remained stable without obvious bursting and swelling, which revealed that no blister occurred inside the coating. EIS results also support the above conclusion, especially for long-term immersion. The potential-capacitance and Mott?Schottky analysis show that the water and ions gradually entered into the coating during the immersion process, while at the same time the coating showed the characteristics of n-type semiconductor. As the time elapsed, the capacitance value decreased and the thickness of the space charge layer declined. The decrease in the slope of the Mott?Schottky curves suggested the simultaneous increase of the carrier density, and the coating was degrading. SEM observation also exhibits an obvious coating degradation after immersion compared with the previous coating without immersion in solution.

Three-Component Ruthenium-Catalyzed Direct Meta-Selective C-H Activation of Arenes: A New Approach to the Alkylarylation of Alkenes

Multicomponent reactions are fundamentally different from two-component reactions, as multicomponent reactions can enable the efficient and step-economical construction of complex molecular scaffolds from simple precursors. Here, an unprecedented three-component direct C-H addition was achieved in the challenging meta-selective fashion. Fluoroalkyl halides and a wide range of alkenes, including vinylarenes, unactivated alkenes, and internal alkenes, were employed as the coupling partners of arenes in this strategy. The detailed mechanism presented is supported by kinetic isotope studies, radical clock experiments, and density functional theory calculations. Moreover, this strategy provided access to various fluoride-containing bioactive 1,1-diarylalkanes and other challenging synthetically potential products.

Ferrocenyl-cymantrenyl hetero-bimetallic chalcones: Synthesis, structure and biological properties

Two new ferrocenyl-cymantrenyl bimetallic chalcones, [(CO)3Mn(eta5-C5H4)C(O)CHCH(eta5-C5H4)Fe(eta5-C5H5)] (1) and [{(CO)3Mn(eta5-C5H4)C(O)CHCH(eta5-C5H4)}2Fe] (2) have been synthesized. Their reactivity study with triphenylphosphine and bis-(diphenylphosphino)ferrocene led to the isolation of phosphine substituted bimetallic chalcones (3-6). Single crystal X-ray structural characterization for 1 and its phosphine analogue (3) reveals their different conformational identity with anti-conformation for 1, while syn-conformation for 3. Investigation of antimalarial and antibacterial activities was carried out for compounds 1 and 2 against two strains of Plasmodium falciparum (3D7, K1) and four bacterial strains. TD-DFT calculation was performed for compound 1 and electrochemical properties were studied for bimetallic chalcone compounds by cyclic voltammetric technique.

Water in a Soft Confinement: Structure of Water in Amorphous Sorbitol

The structure of water in 70 wt % sorbitol-30 wt % water mixture is investigated by wide-angle neutron scattering (WANS) as a function of temperature. WANS data are analyzed using empirical potential structure refinement to obtain the site-site radial distribution functions (RDFs). Orientational structure of water is represented using OW-OW-OW triangles distributions and a tetrahedrality parameter, q, while water-water correlation function is used to estimate size of water clusters. Water structure in the sorbitol matrix is compared with that of water confined in nanopores of MCM41. The results indicate the existence of voids in the sorbitol matrix with the length scale of approximately 5 A, which are filled by water. At 298 K, positional water structure in these voids is similar to that of water in MCM41, whereas there is a difference in the tetrahedral (orientational) arrangement. Cooling to 213 K strengthens tetrahedrality, with the orientational order of water in sorbitol becoming similar to that of confined water in MCM41 at 210 K, whereas further cooling to 100 K does not introduce any additional changes in the tetrahedrality. The results obtained allow us to propose, for the first time, that such confinement of water in a sorbitol matrix is the main reason for the lack of ice formation in this system.

Electrochemical behaviour of ZrTi alloys in artificial physiological solution simulating in vitro inflammatory conditions

ZrTi alloys in artificial physiological solution simulating in vitro inflammatory conditions were investigated for biomedical application. Effect of surface treatment on the corrosion resistance of Zr5Ti, Zr25Ti, and Zr45Ti in acidified Ringer’s solution (pH = 3) at 25 C was evaluated using electrochemical impedance spectroscopy, potentiodynamic polarization curves, and scanning electrochemical microscopy. Thermal oxidation in air at 500 C produces materials with high in vitro corrosion resistance to acidic environments. Higher impedance values related to passivity were observed for oxidized ZrTi alloys compared to as-cast materials. SECM reveals thermal oxidation produced more compact and electrically insulating oxide films.
