Evaluation of the corrosion performance of coil-coated steel sheet as studied by scanning electrochemical microscopy

This work focuses on the investigation of the very early stages of the degradation of coil-coated galvanized steel sheet through swelling and blistering during exposure to chloride-containing aqueous solutions and the possible effect of the zinc-based metallic coating on the degradation at these very early stages. Three types of coil-coated steel whose difference was in the zinc-based metallic coating, namely galvanized, galfan and aluzinc, were considered. Scanning electrochemical microscopy (SECM) operating in the feedback mode was employed to image topographic changes when the samples were left at their spontaneous open circuit potential. Swelling of the coating and nucleation of blisters were observed for all the samples when they were exposed to naturally aerated 0.1 M KCl solution within 24 h exposure. Conversely, featureless and flat surfaces were found when the samples were either exposed to 0.1 M K2SO4 or to 10 mM KCl. For chloride concentrations of 0.1 M and above the chloride ions were observed to promote coating degradation nearly immediately upon immersion in the electrolyte.

THE ADDITION OF 2,4-DINITROBENZENESULFENYL CHLORIDE TO SOME ALKYL-SUBSTITUTED VINYLFERROCENES

The addition of 2,4-dinitrobenzenesulfenyl chloride to alkyl-substituted vinylferrocenes has been investigated in CH2Cl2, 1,1,2,2-tetrachloroethane and acetic acid solutions.Product analyses were carried out by VPC and PMR techniques and reaction rates measured by a spectrophotometric method.The orientation appears to be determined by the structural features of the intermediate episulfonium ion rather than by the site of the primary attack of the electrophile on the starting substrate.A comparison with the results previously obtained with the methoxymercuration reaction has a bearing on the mechanism of the latter reaction.

Study of the protection performance of self-assembled monolayers on copper with the scanning electrochemical microscope

The protection performance of self-assembled monolayers (SAMs) formed by 2-(Pyridin-2-yliminomethyl)-phenol (HL) on the surface of copper has been studied in situ with the scanning electrochemical microscope (SECM). The pitting dynamic processes were observed in sodium chloride solution without the presence of SAMs, but they tended to be inhibited by SAMs if the assembly time was long enough. During the scanning process, the self-assembled method decreases the interaction between the HL molecules and the SECM tip greatly.

1-Methyl-4-ferrocenylmethyl-3,5-diphenylpyrazole: A versatile ligand for palladium(II) and platinum(II)

The syntheses and characterization of two novel ferrocene derivatives containing 3,5-diphenylpyrazole units of general formula [1-R-3,5-Ph2-(C3N2)-CH2-Fc] {Fc = (eta5-C5H5)Fe(eta5-C5H4) and R = H (2) or Me (3)} together with a study of their reactivity with palladium(II) and platinum(II) salts or complexes under different experimental conditions is described. These studies have allowed us to isolate and characterize trans-[Pd{1-Me-3,5-Ph2-(C3N2)-CH2-Fc]}2Cl2] (4a) and three different types of heterodimetallic complexes: cis-[M{1-Me-3,5-Ph2-(C3N2)-CH2-Fc]}Cl2(dmso)] {M = Pd (5a) or Pt (5b)}, the cyclometallated products [M{kappa2-C,N-[3-(C6H4)-1-Me-5-Ph-(C3N2)]-CH2-Fc}Cl(L)] with L = PPh3 and M = Pd (6a) or Pt (6b) or L = dmso and M = Pt (8b) and the trans-isomer of [Pt{1-Me-3,5-Ph2-(C3N2)-CH2-Fc]}Cl2(dmso)] (7b). In compounds 4a, 5a, 5b and 7b, the ligand behaves as a neutral N-donor group; while in 6a, 6b and 8b it acts as a bidentate [C(sp2,phenyl),N(pyrazole)]- group. A comparative study of the spectroscopic properties of the compounds, based on NMR, IR and UV-Visible experiments, is also reported.

Diamond ultramicroelectrodes

Ultramicroelectrode (UME) tips from conductive diamond were fabricated by hot filament chemical vapour deposition. By changing growth conditions, it was possible to fabricate tips with very smooth nanocrystalline coatings, or relatively rough microcrystalline deposits. Cyclic voltammetry data in ferrocene methanol solution was recorded to characterise the two types of diamond. Nanocrystalline diamond displayed inferior behaviour, both in terms of the potential window, and the background current. Two types of insulation method were studied to complete the microelectrode fabrication process. Nail varnish was found to be easiest to apply and produce the best results. Fast set epoxy produced electrodes with inferior voltammetric characteristics. Electrochemical approach curves were measured under differing conditions for the electrodes studied.

A highly efficient synthesis of optically active ferrocenylethylamines via hydride reduction of chiral ferrocenylketimines

Due to using (R)- or (S)-alpha-methylbenzylamine as a chiral auxiliary, and low-temperature regime for reduction of the intermediate ferrocenyl-mono- or 1,1?-bis-ketimines, the corresponding secondary mono- or 1,1?-bis-amines were prepared with high diastereoselectivity. Removal of the alpha-methylbenzyl group afforded the optically active primary mono- and bis-ferrocenylethylamines in high yields. The absolute configuration of (R,R)-3a and (S,S)-3b was determined by X-ray single crystal diffraction. We have developed an efficient and highly stereoselective synthesis of the chiral mono- and bis-ferrocenylamines via sodium borohydride reduction, followed by reductive cleavage of the alpha-methylbenzyl moiety using 5% Pd/C and HCOONH 4. The selectivity was up to 99% de. Copyright

Rh(III)-catalyzed Directed C-H Olefination using an oxidizing directing group: Mild, efficient, and versatile

An efficient Rh(III)-catalyzed oxidative olefination by directed C-H bond activation of N-methoxybenzamides is reported. In this mild, practical, selective, and high-yielding process, the N-O bond acts as an internal oxidant. In addition, simply changing the substituent of the directing/oxidizing group results in the selective formation of valuable tetrahydroisoquinolinone products.

A new ferrocene conjugate of a tyrosine PNA monomer: Synthesis and electrochemical properties

A new chiral ferrocene-labelled tyrosine PNA monomer 1 has been synthesised in good yield in both racemic and enantiomerically pure forms. It is suitable for insertion in various positions of PNA oligomers, a possibility that has been preliminarily demonstrated by synthesising the dimer 16. Moreover, in view of possible applications to nucleic acid detection, a preliminary voltammetric investigation on the electrochemical activity of monomer 1 and its synthetic precursors has been carried out in DMF. It appears that, despite the bulkiness of the PNA monomer backbone, its insertion on the ferrocene group only moderately lowers the latter’s diffusion coefficients and peak currents, thus affording voltammetric detection limits in the order of 10-6-10 -7 M.

Determination of serum glucose using flow injection analysis and highly selective glucose sensor based on composite films

A novel flow injection analysis (FIA) system suitable for measurements of glucose in blood serum is developed. In the proposed FIA system, a new kind of glucose sensor based on composite polymer films and well-immobilized enzyme was fabricated. An electrochemical technique of scanning electrochemical microscopy (SECM), and electrochemical impedance spectroscopy (EIS) were used for the characterization of the newly fabricated biosensor. A wide linear range of 0.1-50 mM for glucose detection was reported in virtue of the new configuration of the sensor and the developed FIA system. The reproducibility of signals was quite good with relative standard deviation (RSD) values for n = 4 injections (typically 5.7%). Animal blood serum was directly injected and assayed in this simulative physiological system. Good analytical recovery of glucose spiked into serum samples, with recoveries in the range of 96.7-105.0%, was exhibited. Under optimized conditions, detection of serum glucose for normal people and diabetics using our proposed method is possible.

Nanoparticle-mediated intervalence transfer

Nanoparticle-mediated intervalence transfer was reported with ferrocene moieties that were attached onto the ruthenium nanoparticle surface by ruthenium-carbene pi bonds. The resulting particles exhibited two pairs of voltammetric waves with a potential spacing of about 200 mV and a rather intense absorption peak in the near-infrared range (?1930 nm) at mixed valence. Both features suggested Class II characteristics of the intraparticle intervalence transfer that mainly arose from through-bond interactions between the metal centers. Quantum calculations based on density functional theory showed that the nanoparticle core electrons served as conducting band states for the effective charge delocalization between particle-bound ferrocene moieties.
